I used to have several instant messaging programs, but they annoyed me, so I no longer use any form of IM.
I am frequently found at Zophar's Message Domain and the Ubuntu Forums. I also hang out on #7chan (irc.7chan.org) quite a lot.
pointlessness now has an official IRC channel, #pointlessness (popn.cjb.net). It's open to all.
My e-mail address is lillymon@nerdshack.com
