Ning is a service that let’s people easily create their own online social network.
Ning.com relaunched their services in Feb 2007. The service allows creators to customize the appearance and features of their website. The user interface is easy to understand.
Creators
1. decide on a web address, i.e., mysite.ning.com
2. drag-and-drop elements—such as text boxes, photos, blogs, video—into a template
3. launch their website and invite people to join
I created workindustries.ning.com in a couple of minutes and I can change the appearance at any time.
Also of note, Ning’s chief technology officer is Marc Andreessen, the founder of Netscape.
