This of course is just my opinion, but I would have to say that the development effort for Linux is outpacing that of the FreeBSD community.
Remember that software being ported to any Unix-like system is a win for all Unix-like systems. FreeBSD can run many Linux binaries through its emulated execution layer, and many apps ported to Linux can be recompiled on BSD with relative ease.

Just because Linux is gaining share doesn't necessarily mean that BSD is losing. It does mean that UNIX is gaining though. :)
