Great idea, but has issues: 1) can't filter profiles to English: I hate to turn down lots of potentially great matches for the pure fact that they're not in English 2) hints that the other person's responses are longer than yours: I find this insulting and rude. If I ask short question and they give a long answer, that's just the nature of the conversation 3) matches are made based on key words: I say that I don't drink coffee, but it would match me with all coffee-lovers
