Social network for night owls MingleNow appears to have been a victim of Yahoo’s recent acquisition of BlueLithium. According to a post on the service’s blog, MingleNow will officially close on January 7th. No official explanation has been made for the closure. We assume that Yahoo simply isn’t interested in maintaining another social network, especially since its purchase of BlueLithium was for its ad network, not its other holdings. See our early coverage of MingleNow here. The product is now in the deadpool.
