Ning: NetScape's Marc Adreessen takes on Craigslist, flickr and just about everyone else
Netscape creator Marc Andreessen shook up the world, but he's at it again, this time with Ning, an all-purpose social-software platform. Ning lets anyone create or contribute to an application, which are then ranked by popularity in the Ning "pivot." Ning's got potential, but right now, that's all it's got. As with any social app, it needs to reach critical mass to really work. If it does, it could be a hit. ~ DownloadSquad
