Tell me what the next big web 2.0 is!

A little bird whispered to me that something is going on in the world wide web. There is a mysterious website called “Tell me what the next big web 2.0 is!“. At the moment you will find only a email notification feature.
I’m not involved nor do i know anything about what’s behind this secret site. Btw. Mato my good old buddy is also linking to this site.
