"Our goal at Backwash is to save you from Information Overload. To filter all content, not just news, and weed out the dross. We do this by grouping people into collaborative surfing communities which let like-minded people find content and products across all subjects. In effect, we are filtering and sorting the Internet by personalities rather than subject matter."
