All these things make sense (and I am making a lot more from AdSense in 2012 than I did in 2003 - partly cause I didn't join it till 2004 or 2005, can't remember) but I don't think it replaces any of the other reasons (including the economy, although I believe that's had the least impact) why AdSense doesn't work as well as it used to for some.

Of course, as always, the question is, what are you going to do about it?
