Been using it since '97 exclusively at home (started with RH 5.2), currently using Debian -testing on both my dual AMD rig and my iMac server. At work I use Fedora Core 2 on a Dell GX270.
As to good forums, try

www.justlinux.com . Also, don't forget
www.tldp.org, and learn how to use the built in help systems (man, info, /usr/doc/, etc).
