Andreessen and Bianchini launch Ning, a free online service where users can build social applications. The service is a product of Palo Alto startup 24 Hour Laundry. Developers can use Ning’s tools to build new programs or work off of clones of existing services.
The difference between apps built on Ning and any of these other services is that we make it easy for developers to build whatever app they want for any topic, interest, group, language, location or product, without a lot of effort. As a user, you get to explore and take advantage of this wider variety of social apps.
