@unoboonex:

While I think I see where you are coming from, that is a terrible example! Dolphin is a software to build community websites... much like a CMS with social plugins. Facebook runs off of a handcoded framework/software that was built internally by the original developers. They are one in the same.

I've developed for and with facebook for two years now - and I will tell you that it is no simple task. I think the biggest issue that software like this and the sites it creates present see more is bloating the internet with community sites that over-cater to their crowd(s).
