Yahoo comments has rolled out a new version that is unpopular with users myself included. This is exactly what happened with Digg before Reddit. Digg's v4 update became so unpopular with users it killed their dominance and now is an after thought. If AOL improves their comments format some you could swoop all those users. Most people click Yahoo news articles for the comments section, now that experience sucks. Make a better alternative your format is not that bad just some simple improvements and let the users express themself and you will be getting far more clicks everyday.
