I have a PR 2 Blog: http://www.showroomlogic.com/blog/ It is dofollow AND all approved comments end up on the homepage widget. Obviously I moderate this, but good knowledgable comments are welcome. Plus, all comments automatically get tweeted and added to a Facebook Update. Please no "great article" comments
thanks for the post. One thing - don't worry about dofollow attributes. What Matt Cutts & Google says about them - it's been proven not to be true.
Show me where Matt Cutts or Google says nofollow or dofollow doesn't matter? I don't believe that for a minute
