Streakr is pitched as follows:
Streakr brings users the best of the web. They simply download a ‘discovery’ bar onto their browsers which, at the touch of a button, finds dozens of new websites that match their interests. They can then rate the sites they like and dislike by stamping them with a ‘thumbs up’ or ‘thumbs down’ icon. Once selected, the URLs are saved onto their personal profile page and indexed for future reference. The sites, which users can also review, can then be shared with fellow Streakrs via the social network.
The politest way of describing Streakr: MySpace and StumbleUpon got together and had a learning impaired child.
