I am looking to develop a social networking site that would have identical operation to Facebook.
The site would have some of the same features but would be a cut down version of Facebook.
The main featured of the site would be the wall, video posting, photos, comments etc. 
As the site become more popular, it would need space to grow and include such things as Apps, & chat rooms.
