Don't insult lolcats by putting them and math in the same sentence.I think we should allow a spam thread to come about naturally. For example, lets say that I create a thread to discuss the finer points of advanced mathematics involved in the string theory and the discussion evolves so that everyone is talking about lolcats at great length and detail. The spam in the thread should be allowed to be continued, but only one such thread like that would be allowed at a time. This way an actual discussion would be going on in the spam thread, plus the thread wouldn't be as inviting since it's not an 'offical' spam thread. The title of "Advanced Mathematics in String Theory" is not inviting everyone to come and post lolcats, you know.
While we're on the subject. Lolcats is pretty kick ass. Now...I don't wanna sound like a queer or nothing, but I think unicorns are kick ass!
