Google Sidewiki is a new addition to Google toolbar. It allows users to read and post comments on any website with a special interface on the left side of the screen enabled by the toolbar. Google is proposing to use an algorithm to rank comments by quality and to link comments to a user's Google Profile.
"Google has developed an algorithm that it says can filter out obvious spam, naughty words, and the classic all-caps technique employed by some of the Internet's more unhinged pundits", said Caesar Sengupta, group product manager at Google. As comments build over time, a recursive algorithm can analyze the quality of past comments using reader votes on the comment's usefulness.You can share your comments with your Facebook or Twitter accounts, and can post a link to a blog item discussing that Web page with a snippet of the text, Sengupta said. Only Google Toolbar users will be able to see the comments on the Web page, obviously, but Google plans to work on an API (application programming interface) that will allow developers to use Sidewiki in other places.
