Go with what's familiar and what I use? Sounds like good advice. But I'd still like to work on a project that needs help more than some of the bigger, more recognizable ones that already have droves of dev's trying to help.
What parts of the FreeBSD project could use some help?
EDIT: Their projects page is pretty cool, I might go with one of those projects then. http://www.freebsd.org/projects/projects.html
