Meta64 is the ultimate Facebook and Google+ destroyer, created to be the Open Source Engine that can power the social web and the semantic web, having superior yet simpler technology to the aforementioned empires.
Currently being started up on Kickstarter.com, the code will go open source soon, and hopefully cause the eminent demise of Facebook in particular. It's already the world's "best ever" news aggregator (merely as an experimental feature), with the news feed located here: http://meta64.com/?link=meta_news&timeline=yes
In the future, the technology will become the backbone of the Semantic Web, and commoditize all web assets and servers, making the "Mega Destinations" like Facebook and Twitter, become a thing of the past, and totally irrelevant.
