Bah.
I've used gnomes plenty. Heck, next week the party in my Bo9S campaign will be ambushed by a gnome swordsage and a gnome ninja/swordsage (and their human swordsage ally, though he hardly counts, being lower level).
Gnomes are one of the most advanced and productive races in my Rhunaria homebrew; the most active in crafting magic items and the most developed in arcane magic (though fairly good with divine magic too, but strictly of the philosophical sort; they dismissed religion as a primitive crutch that held everyone else back and clouded their judgment). They're the most magically-potent standard race in my Aurelia homebrew. Even in my earlier modified-Rokugan campaign, gnomes were one of the most significant non-human races around (though only numerous in the Dragon, Unicorn, and Phoenix lands, having entered Rokugan through tunnels along the northern mountains). They were one of the few non-humans to adopt Rokugani samurai and shugenja aspects, integrating reasonably well with the humans (along with elves).
I've played as many gnomes as I've played humans, over the course of both 2nd Edition and 3rd Edition. More than I've played any other race in D&D so far.
