I have signed up just to endorse this. I've been lurking for entirely too long, and as a random browser I've been assaulted with entirely too much spam, yet knowing that those who are signed in see none of it. I was lucky to run across hubski through some random link or else I'd never know that there are many intelligent and creative people here. The face hubski shows the public is definitely marred with spam the insiders cannot see. Edited to complain that entirely was entirely used too much. Entirely.
