MyPetPeeves allows you to publicly gripe about the things that bother you. All the ones you'd expect are there, like people who talk at movie theaters or bad drivers. What I like, however, are the freakish, nonsensical pet peeves. For example, I have some questions for the person who's annoyed by gum. Is it all brands? Just a certain flavor? Do you mind it if it's still in the package, or does it have to be in the process of getting chewed?
Possibly the best part of the website is that it makes me feel better about the little things that irk me. And when I'm having an absolutely crappy day, I can read up on the misery other people are experiencing at the hands of jaywalkers, Rachael Ray, and (apparently) gum, and feel not so bad.
