Texas-based Pluck, the social media platform provider, has signed a deal with the UK’s Guardian Unlimited which will now use its SiteLife suite, which gives comment, rating, video, forum, blogs and social profile features to readers. The Guardian currently powers its blogs with Six Apart’s MovableType. GU had previously used Pluck’s BlogBurst service to aggregate material from bloggers writing about the 2006 football World Cup. SiteLife lets readers add profiles and displays their latest comments from across the network, as well as photos, friends and personal blog. Telegraph.co.uk with MyTelegraph. [via]
