Gnome Stew has a new feature that I hope very much becomes a regular one (and that does look like the plan): Gnome Rodeo.
It's a big ol' list of links, mostly about GMing but with a few contests for flavor. Having a large, (and I think Gnome Stew aims to become a mighty force in the GMing blog-o-sphere) active, and consistently useful blog doing this is excellent.
If writing something clever about GMing will get you linked by Gnome Stew, that'll encourage people to write clever things about GMing. And everyone who reads Gnome Stew gets easier access to all those clever things people are writing about GMing, because Gnome Stew (and its readers) are out there, searching the web.
And Gnome Stew's multi-author, comment-encouraging, community driven set up makes it pretty close to the best possible forum for this endeavor.
I haven't gotten a chance yet (limited computer access, it's been a busy weekend) but as soon as I do I need to go through my own list of GMing resources. Can't be extolling the virtues of the program if I'm not going to contribute.
