Being the genrous soul I am, I'll share my 'prize' with ar0n. ;)
I'm surprised the method of figuring how many posts were done each month and extrapolating when antivroom was hit worked.

Well, that and lack of competition

Update:I don't recall which data points I hit, but I did take into account the fact that we are growing. Rather than do an indepth analysis, I fudged it. I think I just took off a few days.
