While taking a look to the new proposals from Tech-Cruch 2008 (http://www.techcrunch50.com/), I've found these as been of great interests.

Ok TechCrunch has been dominated by appliance for MS Table and I give my attention to different kind of stuffes that doesn't means they are better!
It's also interesting that there is so much "gazoline" to find new ideas and that there is a structured approach in looking for that by these conferences organized by VCs and a Major company like MS and Google to leverage the growing of an echosystem around their technologies.
It's different from the technological park that we've in Europe. Great approach. In we've to learn a lot from that!
