I just ran across this on Techcrunch and it seems pretty cool. The site is currently down for maintenance so I cant really give any reviews. Apparently you can create your own social network and applications with a few clicks and anyone can do it. With sites like this, WordPress, Drupal, Joomla and other open source systems we wont need developers, scary thought. On the other hand maybe we will need developers more as more people will want to customize their sites as the barrier to entry is almost non existent. Nowadays you can have your own site up in less than 5 minutes.
**I will update this when it comes back up**
