Having thought about this a little more, I have to add that I think the main reason why I'm lenient on other people's titles is because I know how difficult it is for me to come up with one sometimes. So even if the title isn't terribly catchy, I'm willing to give the writer the benefit of the doubt on the story, because they may have simply had a tough time coming up with a good title. An uninteresting title doesn't make me automatically assume that the story is uninteresting too, because I know how hard it is to think of a title sometimes. As I said above, it's the first few paragraphs that make or break it for me.
