I’m about to head up to TechCrunch50 in San Francisco. It’s one of two startup-showcase conferences happening this week, running today through Wednesday. MG Siegler and I will be live-blogging it. Meanwhile, Dean Takahashi and Matt Marshall are down in San Diego this week, covering concurrently-happening rival DEMO. Stay tuned here for all the action, as we’ll be covering both in detail (see Dean’s posts, below, for a taste of what’s to come).
