I wonder if anybody would get peeved if plugin authors added a “Rate me” and “Support” button in the plugin area next to the Deactivate and Edit links.

I've done it in some of my plugins. I'm not sure if it's helped. The problem is that those links don't show up until after the plugin is activated. At that point, I'm guessing most users never notice them.
