Pligg is an Open Source Web 2.0 CMS [1]. Pligg uniquely combines collaborative bookmarking, social networking, folksonomy [2] and blogging. Here, visitors are creator, consumer and judge of the content. Each submitted news item has a vote button, URL and optionally a short description. Visitors may vote or veto and comment on any item. At the end of the day, depending on the vote count, items are automatically promoted to the home page, held in the queue, or permanently removed from site. Being a collaborative CMS, Pligg sites tend to grow rapidly in popularity and traffic.
