News Roundup: Digg gets OpenID, Flickr downtime, 37signals Highrise teaser, Blinkx + Sproose partnership

• Digg to adopt OpenID. Later this year, Digg will be adding OpenID to its site. OpenID, which we looked at back in September, creates a master password similar to what you get with Microsoft's Live ID, but it's not proprietary. (TechCrunch)

• Flickr outage reveals site's scale. Flickr wasn't working yesterday, but fear not--it's back up. The problem mixed up a large number of photos across the site, which quickly led to Yahoo shutting down the service for several hours. Interestingly enough, the outage revealed that at times, the site serves over a billion photos a day. (CNET's Yahoo Blog)

• 37signals shows off a piece of new app Highrise. The first screenshots from the 37signals team have been posted, along with information on managing permissions and groups for its new customer relationship app called Highrise. It may seem a tad on the boring side, but for a collaboration-based tool, choosing who can and can't make changes is important. Previous Highrise coverage here. (Signal vs. Noise)

• Blinkx and Sproose partner for the video search tool. Blinkx, which we checked out at Demo 2007, has partnered with the social search engine Sproose, to provide dynamic search results for Sproose's video search. Sproose lets its users vote on the best results, to make searches more relevant.
