Halflings. I actually started playing D&D before I was familiar with Tolkien, so they've always been halflings for me.
That being said, "hobbit" or not, the sentiment is valid. I HIGHLY encourage all GMs to give a societal name to any 'halfling" people...a communal/racial name/term that is their own for their species. "Halfling" is a purely stature-related term used by the "big folk."
Hairfoot, stout, and tallfellow.
I'm a little miffed by their evolution. I don't care if WotC only shows fit adventurers, they generally don't show plump noncombatant elves either. But I don't understand why they're supposed to live near water now. That just came out of nowhere. I ignore that, an easy task as I'm running Dark Sun.
