I heard a while back - not sure where, it could have been on Slashdot but it escapes me - that FreeBSD was dying. Looking into the statistics just now it seems that's the case. FreeBSD is basically dead on the desktop[0] and is dying, no longer even holding a single percent, in the server market.[1] In the High Performance Computing (HPC) market, Linux holds over 99.8% of the top supercomputers.[2]
