I would like to be able to up vote questions in the question list. (Yes, inspired by Reddit.)
I can think of two situations where this would be handy:
1) If you see a good question, but don't necessarily want to have to visit the question (maybe because you don't have time right now or there are 0 answers)
2) If you see two (or more) good questions, and want to up vote them all before you read a question in it's entirety (maybe so you don't forget the others after your train of thought gets lost in the one question you read it it's entirety)
Very often I read a question title and think "Yeah, I've wondered that!"
Can you think of more situations where this functionality would be a good thing?
Also, how about down voting? I'm more skeptical about that.
