It's not affected me much. I had to trim the number of amazon.com ads on a few hubs, but that was it. That didn't bother me much, as I don't seem to be able to make much with amazon.com. . .not that I've really tried so hard.
I think the new rules are great though! Seeing spam on this site disgusted me, and gave me the sense that this site wasn't always going to be such a great one. I also know for certain that having amazon ads, as the first thing that someone sees on a article, is a real turn off for the reader, and it gives the idea that the content of the article isn't what was important to the author.
