Well, it's hard to judge tbh. Out of the currently active users it's you (@Sniffles), I say currently active because I don't have info on @Kointo and his alt army and frankly, I'm a bit too tired to dig it up now (if that information even exists), maybe in the morning. 3086 posts/19 day=162,42 PPD
It's worth noting that I think it's a bit unfair to compare you to @Insomniac who has an avg. of about 145 posts a day, it's one thing to have a high PPD in 19 days (since Jan 17th) and another to have a high PPD over a period of 124 days (since Oct 4th). Former implies a burst of activity (although not necessarily) while the latter implies consistency so it kinda goes into the area of comparing apples and oranges. We'll probably never have concrete information on this but that's ok, it doesn't really matter in the end we're all here for the comradery, not for the post counts.
