It's always felt on the verge, but has never dropped off the edge. I suppose it's more exciting that way.
the first happened when pg said the site was having some trouble coping with an influx of new users due to some high-profile mentions on other sites. he suggested posting articles about erlang to make the site look boring. i guess people complied a little more than he was expecting, so then he asked people to stop.
the second time was when the site was overrun with articles about _why, right after his disappearance. some people thought it was a little too much, which once again triggered an influx of erlang articles. it looked to me like pg and the editors started killing erlang articles after that, and possibly the _why articles as well.

Was that in the original guidelines, or a recent addition? It seems almost too perfect in response to the comment that iamelgringo was responding to. (As malte pointed out elsewhere in this thread: http://news.ycombinator.com/item?id=978170)
