There's just no innovation to speak of going on in the open source community. Apple, Microsoft, Sun, and other companies are trying like hell to come up with something new. Sun basically redefined the web application over the past few years with Java and related technologies. Apple is trying to design a user interface from a blank slate, and doing a pretty damn good job. Microsoft... well, say what you want about them, but they're trying like crazy to come up with new ideas like Hailstorm and SOAP. Not every idea is a good one, but at least they're new and different.
Let's see some examples of new ideas in the open source community. KDE and Gnome are fighting it out to see which one can be the blandest, least user-friendly desktop environment. Linux, as neat as it is, is caught between trying to catch up to the leading server OS's, like Solaris or IRIX, and trying to catch up to desktop OS's like OS X and XP. It's doing an okay job of both, but not an exceptional one of either. And think of all the brainpower that's being wasted on dumb ideas like the Mozilla sidebar! If only the community rewarded-- through peer validation or whatever you open-source guys use for currency-- original ideas, instead of incomplete implementations of other people's ideas, we might actually see something revolutionary and interesting come out of the open source community. As it stands right now, all I see is a bunch of projects whose names really ought to start with the words "yet another."

Unless you look, most of OSS's most innovative stuffis eiterh half hidden, or elseso pervasive that you forget it's there.
Did someone say something about nothing new comming from the OSS community? It's easy to point at a handful of things and say there's no innovation going on and then forget that if you do the same thing with MS you're stuck looking at WinME, Explorer (not IE, Explorer), Word, and Solitaire. There's a lot of OSS that has become so common that it may have passed below your radar. Pray tell, which non-Free products are Perl, PHP, Python, Ruby, Ocaml, Apache, Zope, SELinux, TrustedBSD, and L4-Hazelnut "exact functional coppies" of? I still don't see Microsoft or Sun's mandatory access controls.
I agree that the OSS community sometimes does things that give the impression that all of the OSS projects are cheap ripoffs. However, I think that at least in terms of operating systems and languages, you'll see that OSS leads the pack in innovation. (No, I don't consider the JVM or the CLR at all innovative. Dis is an innovative non-Free virtual machine, but it's the only one I've seen.)
Oh, and I have an IRIX box. It's a poor excuse for a modern *NIX. (No, I'm not just being a Linux fanboy, Solaris, *BSD, etc. are great *NIXes in thier own ways. (Even Solaris x86). IRIX's only redeaming feature is that it's pretty and I love the hardware.) As soon as I port the code that's on there, it's getting Debianized.
For the record, I'd also like to point out that both MS and Apple's default window managers don't compare favorablywith many of the X11 WMs out there, and it's highly non-trvial to change window managers. (Running X11 doesn't work with most of thier programs, so that doesn't count. Third party WMs for MS OSes suffer stability problems, appearently stemming from an insufficiently reverse-engineered API.)

As an example, early Netscape (pre-Mozilla) on the Mac had a major polling problem. Every clock tick, it checked every bookmark to see if it needed to be dimmed out, whether the menu was dropped or not. Large bookmarks lists slowed it down to a crawl.

Linus' dead-on (Score:4, Interesting)
No-one's patch is entitled to be incorporated into Linus' tree. It is his tree, and he puts stuff in there that he feels is the best. Would you really want Linus putting something in his tree which he didn't feel good about or was unsure of? When Linus puts something in his tree, that's his certification that he thinks it's good and useful. Its his word on that in a sense. The minute he starts putting stuff in because people pester him, his word that something is good and useful to his knowledge becomes useless.
Chances are that if the patch is good, Linus will accept it provided he's given enough time to properly evaluate it. Linus is a human being like the rest of us. He can't thoroughly evaluate hundreds of patches coming in a week before the feature-freeze deadline. Try to give him the same breathing room to do a job you'd give anyone else. Also, remember, Linus doesn't have to do anything. He's doing this voluntarily as a service to the public. If you think you're patch is good and useful enough to be incorporated, and Linus rejected it, then go out and prove that its good. Put it in you're own tree or convince a vendor to do so; then people will use it, and if its good, word will get around. Once that happens, more likely than not, Linus will put it in his tree.
I've submitted about a hundred articles to Slashdot, many of them on what I thought were good "your rights online" issues. Do you know how many submissions of mine have been accepted? 1. It was on Creg Ventor, the man who used his own DNA to help sequence the human genome; ironically, I thought that was one of my worst submissions. Yet, believe it or not, you don't see me whining to the editors of Slashdot or in the discussions about it. I realize that many many many other submissions have been made, that the editors have to choose what they feel is best, and that they have to create a variety; I also realize that they're human beings.
Other people would do well to do the same in regards to patches.

Summary (Score:5, Interesting)
There is a patch that has strong vendor support (like vendors have already signed contracts involving services from this patch).
This patch is a service offered on many other commercial unixes (Irix, Solaris, AIX, etc..)
Linus considers this patch:
a) to be dangerous
b) to be difficult to test
c) likely to have the most problems on the x86 platform which is Linux's home platform
d) supporting it might add long term maintainability problems to the kernel
The kernel hackers whom Linus trusts seem to agree with his assessment.
What Linus wants is
a) for the vendors to support this patch over a long period of time on a wide range of systems.
b) For there to be some evidence that Linux users (as opposed to Linux vendors) actually want this feature.
So what you have is a fight between big guns: Suse, United Linux, IBM.. and Linus.

Mac OS could be counted as a *BSD, but that is a very recent trend. The Mac following wasn't built because of the new *BSD foundation. OTOH, I know of no one that is using Linux, FreeBSD or OpenBSD that is using it because it the foundation of another semi-emulated OS environment. As an example, I haven't seen anyone that is using Linux and wine/winex/vmware/win4lin/basilisk/etc... as their main operating environment ( sans Linux apps).
Still, if Apple were to release an X86 version of MacOS 10.2, I would buy a copy to try as my main desktop. It would be to try Mac apps, not run FreeBSD specific apps, I would just use FreeBSD if that was my only goal and I assume the goal of most Mac users is to run Mac apps, not FreeBSD stuff. That makes for some stretching to count MacOS 10.x as FreeBSD. Do Mac people run two OSes? If they have to pick between describing their computer as running MacOS or FreeBSD, which would most of them pick?
I have been running *NIX type OSes for 17years starting with VMS on a microvax, basically because I like things that work. Linux seems to like the followthe same combination of requirements. *BSDs tend to have less support for the hardware in my systems than Linux and they both pale to Windows. Sheer support numbers don't mean as much to me and Linux is the happy medium.
Linus and crew have found a formula for developing a *NIX type kernel that many others have decided makes a good foundation for their OS distribution.

I highly doubt that any of the BSD maintainers would accept a patch either. It goes back to whether the trust is there, and evidently these guys don't hold Linus's trust.
Not much controversial here.

They do. Subscribe to the LKML [kernel.org] and post it there. Pretty well all of the important developers of the kernel (most trees) frequent it. Ok then - we have two VMs - Riks and Andreas's. Since everyone's supposed to get equal input and nobody is supposed to control the kernel - we're supposed to have both of them in play?Would you like to write the code that keeps them separate depending on which box I fill with an 'X' in menuconfig? What about all the other aspects of the kernel where we have two, five, ten, or a hundred different patches that all do the same thing? I don't know about you, but I don't really fancy downloading a 500MB Bzip2-ball of kernel source. HDDs and bandwidth may be cheap, but come on, there are limits.
So in short, if you don't like the way Linus manages his tree - branch. Take the entire code base of any of the trees you'd like as a starting point and implement your anarchist's paradise. Let me know when it becomes stable and I'll give it a whirl.

No. Almost all open source projects have one person or a small group in charge. Why would this be "against the whole idea"? You're just as free to make your own changes on your own darned computer, no matter how many people are in charge of however many "official" trees. The so-called "official" trees exist merely for the convenience of those who don't want to bother to roll their own each day, and the people in charge of those "official" trees are only in charge because they've earned the trust of those who use their trees.
Shouldn't everyone have input of equal value?
No. This is a meritocracy, not a democracy. The people in charge end up in charge because they've proven themselves by the quality of their work. Remember, an "official tree" only remains "official" as long as people are willing to call it that and treat it as that. "Official tree" in open-source terms is a de-facto label, not a de-jure one.
Or to put it another way, only input of high value is valued highly.
Any more silly questions?

This is Linus'es tree. He get's to decide what goes in and what doesn't. But, because this is open source, others can make a copy of his tree and add whatever they want in to it. But they have exactly ZERO power to force their code in to Linus'es tree!
This really is no different from ReiserFS. It was used by SuSE and other for a long time in their kernels before it became part of Linus'es tree. Same thing will happen with LKCD. Vendors will make it part of their kernels, and it will be merged (propably) in 2.7-tree.
