An anonymous reader writes "Key Linux kernel contributor Jonathan Corbet has admitted the developer community can be intimidating and hard to break into. He highlighted the issue during his Linux.conf.au presentation on the Linux kernel. Corbet expressed concern about the exclusivity of the kernel community, but says it's doing well regardless. He said in a period of just over a year, 55,000 individual changes from 2,700 developers (representing 370 employers) were made to the kernel, equaling 2.8 million lines of code. Corbet called the process 'alive and active.'"
