I haven't noticed any difference so far in anything. In fact, september was my best month in terms of adsense which seemed weird.
CJ sales and similar affiliate sales were down in September for me. But the number of clicks to various advertisers was about the same. That told me people were still looking for things, but less ready or able to buy. Economic crisis, sure... Are you spending more or less right now on unnecessary items? I have been drinking less at Starbucks...
Haven't noticed any drops only that one affiliate decided to drop me and not tell me why - when I questioned it they said it was because I had their "competition" on the same page! It wasn't because I was making them money!! Say what.............
