>>30
You misunderstand. The idea is to ostensibly be a different person for each session, not each message. If I say something on IRC and then say something else on IRC 10 minutes after that, I don't care that you can link the two messages. I just want to be sufficiently anonymous that you cannot link what I'm saying on IRC with what I said a matter of days, weeks, or months ago, or the message I posted on /tech/ earlier this morning, or the essay I just put up on my personal (non-anonymous) website, or whatever.

Likewise, I won't be horribly upset if you figure that I'm probably the same guy who posted >>29. I don't need to be that anonymous.
