As has been publish on a zillion weblogs today, a group of the most significant search engines (Google, Yahoo, and MSN Search) and weblog tool publishers (Sixapart, Blogger, WordPress, LiveJournal, etc.) have agreed to implement a new tool to prevent weblog comment spam.
The idea is simple. Weblog tools will tag links left in comments with a rel=”nofollow” attribute. When search engines see this, they will not follow the link and as a result, comment spammers will not get a bump in the search engines by leaving rogue links.
I can understand that comment spam is a serious problem. It has been quite a problem for me here on this weblog. However, I would like to add my small voice to those who are concerned about the ramifications of this new tag.
Tagging all links in comments left by weblog readers means that none of these links will contribute to the great hive mind that is Google PageRank. There are loads of great and valuable links in weblog comments.
Some systems will likely turn off this feature for comments from “trusted” people, such as logged-in Blogger users, TypeKey users, or LiveJournal-friends. However, this limits the wild-westiness™ of weblogs and the ability to benefit from the mass of communication by improving search results.
I applaud those involved for working to curb weblog comment spam. However, I fear this may hurt the web in the long run.
