So this is what CrunchWeek is like without adult supervision.

Leena Rao and Colleen Taylor, the show’s two regular hosts, were both out of town this week, but there was still plenty of news for TechCrunch writers — specifically Greg Kumparak, Alex Wilhelm, and me — to talk about. We weighed in on the anticipation around Twitter’s IPO filing (and what was revealed in its S-1 filing), the shutdown of anonymous Bitcoin marketplace Silk Road, and reports that Amazon is developing its own smartphones (one of them with a whopping four cameras).

By the way, apologies for the occasional bursts of random background noise. I blame the gremlins hiding in the TCTV studio.
