That was my experience when I tried Digg a few years ago. I thought good content might rise to the top, but what rose to the top was usually something posted by a power user. Often, multiple "nobodies" had posted the same thing, or a close variation, earlier but got no traction. I wasn't motivated enough to try to build a posse of mutual back-scratchers.
