A sense of community remains is a powerful feature of Linux. Few tools reveal the power of open source, and none more clearly link this community better than IRC clients. Dozens of clients exist, from the small and powerful (irssi) to the complex (centericq). I prefer a lightweight gui: Konversation.
Think of IRC as an open window to hundreds of open source projects, where developers often respond to questions from users on every imaginable subject. Freenode, a service of the Peer-Directed Projects Center supports many popular interest areas.
I recommend the use of freenode, a service of Peer-Directed Projects Center. Freenode host a very comprehensive list of groups related to most major peer directed and open source projects, like Apache or KDE. If you are new to IRC it would be wise to review the general questions and user registration requirements in the faq. Other projects, for example Debian, uses the OFTC network.
