I've been doing adult websites since 1998, and I still could go either way on if a summer slow-down occurs. Summer definitly isn't "bad", but it does appear to me that the actual rate of growth may indeed slow down just a smidge.

If I had to come down on one side of the fence, it does look like the rate of growth from Spring-to-Summer is smaller than that of Summer-to-Fall, Fall-to-Winter, or Winter-to-Spring. That being said, all growth is good and each quarter is always better than the one before. Consecutive growth month after month is all I really care about

"vacation period" -- What's that?
