Is there a way to hide threads/topics?

I keep seeing ridiculous stupid and repetitive threads in the iPhone forum this week, one is already complaining about a "yellow screen issue" about a product that hasn't even been announced yet. I think a "hide thread" feature would be great so I don't have to see that crap. Self-censorship would also save moderation so we don't have to voice our opinions about the stupidity of such threads.
