"It would be a much more engaging experience if we talked." I bet if it was just a little more crowded in here, people would talk more. Right now it's kind of like being on the subway.
Well, how do you determine crowded? I would use some ratio of unique visitors/day to new posts above the fold for those user/day. Essentially, it would be people/content. We have the content, we just don't have enough people.
