There are some things like ZFS, that keep me on FBSD.. but that's only 2 of my servers. The biggest reasons are that it's what I know; and that I have a collection of software projects created over the past 15 years that run on FBSD, most of which do not compile cleanly in Linux or have fbsd-specific dependencies. So until I port them, FBSD is the only option. I'm not the best person to ask to advocate FBSD. I'm planning a switch to Debian over the next year or so. Later this year, I'm planning to switch my mail servers and database servers to Debian (since those don't rely on my code). Then the porting should be finished, and everything else will switch except the ZFS servers. The ZFS servers should be gone by mid-2014. Why? Lack of virtualization support is the biggest problem.
