This year at OSCON it seemed that you couldn't throw a stone without hitting someone from Microsoft (and in fact, I'm sure several people did). They were working very hard to make themselves known, and working desperately to change public opinion
of Microsoft's involvement in the open source community. Linux.com's Nathan Willis took a look at what they were preaching, with a hefty dose of skepticism, and tries to postulate what the "angle" is. Of course, the powers that be at Microsoft may have finally seen the writing on the wall and felt the pressure from Google enough to alter their strategy a bit. For now I guess we'll have to wait with guarded optimism (or laughable contempt, depending on how old/jaded you are).
