For a while I was averaging over 50 posts/day not in that sort of thread. Yeah, that was more time than I probably should've been spending here but I enjoyed it. That said, I did spend my first couple years not posting very much at all so no way I'm near the fastest to get there.

ETA: Between July 22, 2010 and December 15, 2010 I had 5,444 posts.
