The F-List 
CommunityCommunity-building is all the rage in the online arena these days, but pulling it off requires much, much more than just talk. We won't beat you over the head with already blown-up sites like Friendster, MySpace, or Facebook here; instead, we focus on a handful of still-burgeoning community sites founded on incredibly cool ideas. -Jocelyn K.

Dodgeball.com
Available in 22 US cities, Dodgeball allows you to tag your friends via SMS message when you're out on the town. Just text Dodgeball when you plant yourself at a venue, and it automatically alerts all your similarly checked-in friends within ten blocks. Plus, how many services notify you when your crush is in the nabe, or let you send Flavorpill events to your phone? -Jocelyn K. GleiFlickr.com
There are numerous ways to share your digital photos with friends, but Flickr takes the cake for breezy usability and just the right functions. Easily upload scads of photos from a Mac or PC, integrate them seamlessly with your blog software, and change permissions from gallery to gallery — thus keeping the fetish pics nicely cordoned off from the family ones. -Jocelyn K.
