User Bit Cannon shows us how to get GNOME 3 desktop environment set up on FreeBSD. Follow the link below for the full set of instructions, including their thoughts on GNOME.
I’m a FreeBSD fan and (small scale) donor. It was the first open source OS I ran back in 2000 and I continue to use it today. In fact, this very blog is hosted on VPS running FreeBSD. I like it because:
it’s compact and efficient
stable and reliable
built as an integrated, consistent base operating system
released under a permissive licence
