News Corp.'s MySpace social network is currently testing a service that scours the web for news stories and lets users rate them, aiming to attract more advertisers. The service, called MySpace News, resembles a mix of Google Inc.'s Google News, which collects stories and arranges them based on thematic similarities and Digg.com, which displays stories suggested by its readers and displays them according to their popularity ranking. The service adds a social element to traditional news consumption by giving readers the ability to determine what becomes the top news on MySpace. The news service, long rumored, will have 25 main topics and about 300 sub-categories ranging from celebrities and gossip to autos and fashion. Also, news publishers can ask to have their news feed removed from the MySpace service.
