How do you let people know what your "pet peeves" are?

I'd say making a pick for a particular question about pet peeves would be a perfect way to do it. In addition, there's always the option of posting a new forum thread in an appropriate club - the one that springs to mind is the Fanpop Users club, since your pet peeves are about you. But the most obvious (and, I think the most appropriate) way to do so on Fanpop would be to write an article, again in an appropriate club.
