Second this.

It's bad enough when every site makes you go through and pick exactly which invasive cookies you don't want, but I'd like to call out Stack Overflow/Stack Exchange as a particularly bad offender here. They present the dialog each and every time you visit one of their sites. It's beyond annoying, and, were it easily possible without sacrificing my ability to decline their cookies, I'd block that dialog element entirely. Maybe this is a good job for a browser extension?
