Seems like an awesome idea to be honest. A few things though, in my opinion, as has been previously stated, it shouldn't be called power +, it should be something different, completely on it's own. As well, will this group ever max out in members? What I mean is, as FK grows older, the older members will have an increasing chance of joining this group. Then as more and more members join, the concept is ruined, can this be prevented? Last point, the 1,000 HQ post thing is a pretty high target, but what defines high quality? If high quality is a post that's over two lines than many members could have it. However, many members who make HQ posts don't have a high amount of posts due to high quality posts not being able to be written quickly or often. Those with high enough post counts may have 1,00 posts they do deem HQ, but what if others don't? How will that "high qualityness" be determined?
