First of all, we're not all gentlemen.
Second of all, remember correlation is not causation. It's not at all clear to me that the domain name is the entire issue. That's a pretty big drop. (And a lot of other people have seen large AdSense drops over the past year) Were you using placements before, and are you now? Are you seeing essentially the same types of ads as before? Is it possible that your domain change caused you to be put in a different category by Google, such that you would be targeted by different advertisers? Are people coming in from the same keywords, the same countries? There's a lot to look at before I'd just haul off and switch domains. (To be honest, I probably wouldn't have switched in the first place; but I'm reasonably sure that if you switch back you're not going to magically see the same earnings again)
