"Don't believe in yourself! Believe that I believe in you!"

If you're trying to quote Gurren-Lagann here, I believe you botched the quote. "Believe in me who believes in you!" But maybe it was dubbed differently. In any case, I do find some amusement in your approvingly quoting a show which was more or less premised on a rejection of rationality. "Throw away your logic and kick reason to the curb!" I'll have to remember that for the next anti-rationalism quotes thread.

But anyways, I did like this post, although as you implicitly concede it's just one narrative of community development among many. I'm sure that there have been as many communities to have fallen due to despotic moderation or impoverished by rigid ideological guidelines as there have been ruined in the ways described in the OP. Oftentimes the "idiots" who "ruin" the comm are actually the lonely voices of reason. It's a fine line to walk, and I look forward to someday seeing a modern-day Machiavelli write a tract on "The Internet Community Moderator". Because it really is that tricky.
