I just can't seem to learn my lesson about not bothering to click on Valleywag links with provocative titles. Anyone with more time their hands than I want to write a Greasemonkey script to hide them? You can call it Valleywhack.

We were just talking about this problem today. I could write something to let users list domains they don't want to see stories from. Would that be useful?

Right now Valleywag is the only killfile-worthy offender that I can think of, but yes, it would be useful.

A site would have to come up pretty often for me to want to block it. I don't remember ever seeing the British tabloids on here before.
