Pros and cons, I guess.

I like the convenience of "what you see is what you get" this comment box business provides, but I don't like how large a shadow it draws over the rest of the page. I liken the capturing of right-clicks to when people try to stop you from looking at their precious HTML source code by popping up a "Not allowed" message when you right click anywhere on a page. It's infuriating, and ultimately gets in the way eventually.

Though... hmm. That gives me an idea.
