I think what makes this the most interesting of all is that from the standpoint of stomping out knowledge of the key, AACS's attempt at censorship has resulted in a flat-out catastrophe.<p>I don't own an HD-DVD player, and have never made any effort to learn how to break its encryption. I'm sure many people are just like me. If it wasn't for the user revolt I wouldn't know about it. (I don't typically use Digg, and use Reddit only rarely)
This is a really interesting case study. Especially since it seems as if hundreds of new users are migrating over to Reddit. I wonder if there will be any noticeable impact in Reddit's traffic because of this.
Update: every single story on the Digg front page is now related to the HD-DVD key. This is certainly an interesting event in the history of community based sites.
