The Best of the Web
I'm a nominating judge for the Webbies again this year, in the Community category. We're starting to discuss candidates for the nominations, and I'd like to pick your brain. If you can recommend any Web sites and services that meet the following description, email me, and I'll consider it for the mix.

Community: Sites creating and facilitating online community, connectedness and/or communication around shared interests. These sites can target either a broad-based or niche audience.

Thanks for your help!
