POPrl is a new site developed by the recently launched uLiken.com. The site takes a different approach to displaying popular links that have been user submitted, setting up their algorithm so that the “most POPular” urls that make it to the homepage are the ones that have been clicked on the most. Links are submitted without ever having to register or do anything besides entering the url into the site’s link shrinker. You then have a shortened url in TinyURL fashion that you can post to Twitter, your various social networks, or anywhere else to try and increase the virility of the link in the hopes of getting that content to the general public viewing the POPrl page.
