Community

One of the best reasons to use FreeBSD may be its community. The mailing lists are full of people who are both helpful and respond quickly. Questions get helpful answers, often 90% of the time within the hour. What other OS can match that? Even if a question doesn't truly apply to the specific mailing list, a helpful reply will likely come. FreeBSD's community is what keeps a lot of people with the OS, never mind the stability, easy install of programs and all the other things which make FreeBSD that much more helpful.
