Hey,
I am starting to work on one of my sites,
www.AllDotNet.com
I used to have a different script and I made a lot more from adsense even 6 months ago than I do now, I don't know if it is because the templates/script and layout has changed, or it could even be that adsense payout is just a lot less, but I doubt it since the earnings have gone down a lot and my traffic has gone up a lot.
You can see the category listings here:

Anyone have any suggestions?
