In order to continue to grow the site, we need to work on promoting the site. It isn't something that is just going to happen, we need to be proactive about this. There are several ways to do this, please see this question which needs your input!
Robert recently posted on the blog: A recipe to promote your site. I like his suggestion of narrowing the focus. So, in the answers to this question, let's identify experts in the field that we can reach out to. People that can help us get word out about the site, draw users in, and perhaps even have a presence here. We can worry about how to get in touch with these people later, but we need to come up with the who first.
