Déja vu
Here we go again, as per usual. Then, it was DOTCOM, now it's CloudCrap (TM) and social media, in a couple of years it will be something else.
The sad thing is: among a lot of pointless, useless, stupid ideas are always a few with real potential, and the bursting bubble will kill most of them as well.
