Not really. Getting a community off the ground usually takes a lot of effort. As an example, when Reddit was starting out, each of the guys working on it (maybe they were two at the time), had lots of different usernames, and they'd basically make fake conversations all over the place. That way there were always some people talking so it would be easier for people to join in on the discussion. I suspect the first step would be for us to just try to break the ice and start having conversations on here. I at least think the "replies" section is a good add on - I hadn't noticed it until recently.
