Create your own social network!
Until now, if you wanted to create a social network for your self, the answer was almost certainly Ning. Today there are over 115,000 networks there and it’s growing.
When it was launched, October 4th 2005, it was a revolutionary idea that Fred best-described in TechCrunch:
In the recent past, every time a web2.0 service is launched, some opensource alternative is also released. Well, yesterday I found an interesting article in the .net magazine where it lets you host your own social network. It’s easy to do, you’ll just need a PHP+MySQL server but that’s what it gives you the power over Ning. You can change it around the way you like and add or remove more features, and so on.
I don’t believe this is a Ning-killer since the average Joe doesn’t have a hosting account, nor time to set it up and hack around. He’ll just go over to Ning, create a social network and play around with the theme editor. And users of multiple networks will share their Ning ID!

The list of features is impressive, it even comes with OpenID authentication and podcast support, but it will come to whether it is easy to install and start working with.
