My biggest peeve about gnomes (other than the fact that they are a bunch of nancy boys, natch) is that WOTC seems to have them confused with Dwarves.
Whenever they mention a fantastic weaponsmith, they mention gnomes (not dwarves).
I go to gnomes for finely crafted-- but utterly useless-- crap, like jewelry, clockworks, etc. You want a weapon, you ask a dwarf.
They recently did an article on giant killers. Dwarves? Nope. Gnomes!
Aaaaaaaaargh!
