Some quick thoughts on facebook and twitter traffic for your site...

Some sites have been known to get even more traffic from Facebook than they get from Google. I suggest setting up a Facebook page. Compete recently found that demographics of Facebook users strongly resemble demographics of Internet users in general. Essentially, that means that people of all kinds are using Facebook. You have potential customers on Facebook.

For some sites, twitter is their main traffic source. Now that Google is including real-time search in their search results, Twitter itself is getting more traffic. For newsy Google queries, newsy tweets are getting a lot more exposure. Twitter also has a way of making content go viral (much like Facebook does, only on a much more open and public level).
