Just how big is Social Media / Web 2.0 ???

I think, to say how big it is, would be to say there is a limit to it - and after visiting the below sites, you tell me, is there a limit?

Wikipedia - The term "Web 2.0" (2004-present)is commonly associated with web applications that facilitate interactive information sharing, interoperability, user-centered design,[1] and collaboration on the World Wide Web. Examples of Web 2.0 include web-based communities, hosted services, web applications, social-networking sites, video-sharing sites, wikis, blogs, mashups, and folksonomies. A Web 2.0 site allows its users to interact with other users or to change website content, in contrast to non-interactive websites where users are limited to the passive viewing of information that is provided to them.
