I honestly can't tell if this post is a snarky complaint, or a honest piece of information, or what. - though I think snark is slightly more likely.
This is a problem I frequently experience on LW and almost never experience elsewhere. I'm never sure if it's because of the context or my perception of the typical LW user.
#lesswrong on Freenode, which used to be the official unofficial LessWrong channel, has been re-designated as a private hangout reserved for, roughly, ggreer/AngryParsley, efm, realitygrill, rsaarelm, ksotala, gwern, Grognor, chelz, cwillu, Boxo, nshepperd, ivan, mstevens, and jandrog. You're still welcome to speak there, but only if whatever you're saying is interesting/important to one of them and the op.
For less constrained conversation, go to #lesswrong-alt (unregistered; recommended by #lesswrong's op), also on Freenode.
EDIT: #lesswrong's rules have been changed to "behave like decent human beings, give ops liberally to channel regulars, don't ban without warning or if most people disagree". This PSA is hereby retracted.
