If I accidentally vote uninteresting, how do I undo it and change it to interesting? Thanks?

These people may have many interesting and informative things to say.... but if they find the idea of saying it scary, we will never hear it. I think when something is not offensive or inappropriate for reasons like those Opher mentioned, and you simply personally find it uninteresting, there is a great way to vote it as such without being unwelcoming to anyone: Just ignore it. Now that I think about it from this angle, I feel like the most ideal thing would be to have a "vote inappropriate" button instead of a "vote uninteresting" button.

That's just my opinion, after seeing these "uninteresting" or "I don't like this" functions become a way for many internet communities to gradually incubate nastiness, clamouring for attention, and taking out your frustrations and dissatisfactions with the day you've had or your life in general . I like anything that prevents this, and I'm kind of unsupportive of anything that gradually encourages it, even unintentionally.
