The Syndicated Web is filled with communities on just about every subject. Whatever the topic, odds are there's a community of experts and enthusiasts that are already talking about it. But unless you're already famililar with the community, you may not know where to find it.

PubSub's Community Lists are miniature roadmaps to those influential sites. They combine human expertise with LinkRanks, PubSub's method of comparing sites to one another by scrutinizing their links. A Community List tells you which sites to keep an eye on and which sites are leading the conversation from one day to the next.

We're kicking off the Community Lists effort with four lists, but we want more, more, more! To do that, we need list editors. If you'd like to be one, get in touch with us at feedback@pubsub.com and let us know your area of expertise.
