That's funny, I searched for "Irrationality Quotes" and that led me to believe it hadn't.

EDIT: Actually now that I think about this...Alicorn may of course not even be suggesting that it's a bad idea due to a previous thread in 2011, but just in general, if the last time the topic came up was 3 years ago, it's probably fine or even preferable to bring it up again in some form if people found it interesting before. I'm sure there have been a few new members in the last 3 years, and a few more irrational things have been said. In general, people discuss various relevant topics more than once, and a time horizon for repeating them would probably reasonably be on the scale of months at the most. Otherwise, it's guaranteeing the slow death of the site.
