If you track our stats on Area51, you'll see that our percent answered and answer ratio are both, B"H, in good shape, and our questions per day is in a decent place and rising steadily. However, our user count and visits per day have been more or less flat, following a big jump when this site opened on SE 2.0. What this tells me is that we're doing a great job of generating great content and answering people's questions, but we have work to do in growing the community and making more outside people aware of the great content here.
One way to make more people aware of our content is to get people to link to content here in their blogs, Twitter feeds, Facebook feeds, etc., especially if they are influential people. How can we get prominent writers, bloggers, Twitterers, etc. to link to judaism.SE content?
Update: Take a look at this blog post for inspiration.
