A little over a year ago Google introduced the nofollow attribute. A lot of software publishers, and SEs jumped on board. The original intent of the attribute was to cut down on blog comment spam. Unfortunately that has not been the result of the attribute. What has happened is a lot of confusion in regard to what does the no follow attribute really mean? I just posted a rather lengthy article (for me) on spam-whackers about the nofollow
issue. For those not familiar with this debate there are a lot of links to background information. Adam Lasnik of Google commented in regard to my article so I think it is worth your time to read.
