One of the items I have neglected to mention in the entry I wrote about the revised AdSense Terms of Service was that you can now openly discuss how much money you are making. Before this was against the TOS, and if you were caught releasing this information, you could have been kicked out of the program.
Talking about income is a touchy topic for many in the United States. I would never ask someone, "hey, how much you make working at that place?" If someone asked me that, I would be shocked and possibly a bit disturbed. But I did spend some time outside of the US and in some places, there is nothing wrong or even upsetting about asking someone a question like that. My brother told me, he was once on a bus in a country outside of the US, and someone simply asked him, how much does he make. He was shocked, but the guy explained that this is something that is discussed openly in that culture.
Anyway, back to my point, if you want to discuss your earnings with AdSense, you now can and many are at WebmasterWorld.
