...I could agree that nessie "was" the biggest change in years until now. I think what's happening right now though is way bigger and more comprehensive than anything I've ever seen with Adsense before and it's gonna require people to break out their designer hats all over again and in a very big way. I know these changes haven't really worked with some of my layouts out of the box.
@simplo Just for some context, how long have you been seeing round buttons? Some reported it about a month ago I think, I didn't see them until much later.
