I just thought that I would point this out and see what others have to say.
The one thing that I keep finding when reading through linux.com is that I'll find an article that I find great and I want to indicate it as something I enjoyed by a "digg"-type button, but all I have is a "Favorite" button.
That said, I realize that there is a real Digg button, but that would mark the article up in the ranks on the actual digg site.
Request: Add a button that I can use to mark an article as worth reading. (I can mod up comments, but why not articles?)
