Ask HN: Would you be interested in hacker "small groups"?

One of my chief gripes with Hacker News, and with other similar sites, is that they get to a point where they're so popular that a lot of decent content gets overlooked, simply because there's so much pouring in at once. I was thinking of borrowing a technique often used by churches, which have big general services, but then break people up into "small groups," so they can have more intimate discussions and actually get to know one another. Imagine if there were a site like HN, but it consisted of "small groups," where each group had maybe 15-20 members. Each group would only see content posted by others in their group. That way, when you post something, it may not get thousands of views (as it would if it hit the HN homepage), but it would be less likely to get overlooked completely, as things often do on HN unless they gain a critical amount of traction in a very short time. So what do you think? Would you be interested in the "small group" approach? I'll only build it if there is evidence of sufficient interest.
