Are you 2.0?

I've spent too long focusing on the back-end of the Internet, how the routers and switches connect together, MPLS, SDH, WDM; and all the other alphabet soup acronyms. Recently I've been spending more time as an Internet user and have come across a number of tools which are apparently Web 2.0. Some of these I love, and I'll mention a couple of them below, others I've tried and to be honest they do nothing for me. Seems I'm not alone in this regard, found this post by my old mate Dan over on vox. Am I Web 2.0? Maybe. Or maybe I'm just too old...
