Twitter is Obsolete
Let's face it, you try it for a while then you become a lurker.. then you give up..
You already have too much noisy irc channels where often something really interresting is happening and where you can engage in a discussion, not in a @otherdude public broadcast style. Tom is so right.. it's the crappy irc channels such as #vlaanderen etc where notthing really happens all over again only this time integrated with SMS and mail.
Yes twitter makes a cheap Nagios 2 SMS service and that technology has it's uses .. but I`m sticking to Jabber and irc.freenode.net where the technical discussions happen.
Goodbye Twitter !
