I will admit that I have seen a jump in sales, etc after 100 posts, and more so after 120.
However.... taken with a grain of salt, it may just be coincidence that the increase could be coinciding with Ren faire, Comic-con, and festival season.
(I was on Etsy some years ago and just recently came back, so a trend of a few months is hard to judge... starting back up in February was a little disheartening at times!)
