Kevin Rose and his Digg crew recently released a screencast of their new commenting system for their tremendously popular social recommendation service. If you look carefully at the video, you should soon be able to digg the comments within each Digg (I know, talk about meta!). While it may look like an overkill, it might help with the general complaint that the quality of Digg content has gone down. If you think about it even deeper (think hard!), this feature is likely to polarize Digg users’ sentiments even more. It’s a really interesting social experiment to see if the state of Digg actually gets better or worse. Bow down to Dion of Ajaxian for the headsup!
