This is my list of pet peeves.
-Church Bells. Apparently, nobody remembers how to ring them properly, so the tunes come out so butchered that a first grade music teacher would cringe in horror. Stick to ding, dong if its gonna sound like crap.
-Inappropriate restaurant music selection. If I go to a chinese restaurant, I don't want to hear fucking country music. It's call atmosphere people.
-smooth jazz – all of you should die. and so should your djs.
-non-human readable links – if you have a hyperlink comment, either describe, or let the url describe it. especially if the message on the linked page is the title. some douche this morning wrote 'john travolta has been in a lot of bombs" where bombs linked to the imdb page for battlefield earth. nice punchline asshole.
