As an argument, not that I'm arguing: In the summer, people have more money, because as we all know everyone's drained after the Christmas season... plus, a lot of people like to take their vacations in the winter... Also, keep in mind that the online population is growing at a faster rate than ever before. Just playin' some devils advocate.

What kind of differences have you guys noticed between seasons over previous years? Are we talking 50% worse off, 10% worse off, etc..?
