Were I to tag this week, it would look something like this: SXSW, Facebook redesign, Foursquare, Christopher Walken, not Christopher Walken, Rackspace, Rob Cordry. Allow me to explain…

News from the Social Media Vortex

–SXSW occurred and a good time was had by all, especially Foursquare which seemed to win the “Twitter of 2009″ buzz award during the week. What’s Foursquare? It’s the new version of Dodgeball. Not familiar with Dodgeball? It’s a handy mobile stalking tool.

–The Facebook redesign occurred and is not receiving the warmest of receptions. In a polling application created on the site, 954,000 users so far give it a thumbs down, with 58,000 approving. Will the masses cry loud enough to be heard? I’m working on a longer blog post about this, so check The Guidewire later.

–Robert Scoble disappointed me by neglecting to mobilize his army, at least for the moment. Instead, he’s launching a new content community with partner Rackspace, called Building 43. I’m a little fuzzy about what the new site is exactly, as his explanation involved Creative Commons, cloud computing, interactive videos, and something about boats in a tide.

–My initial excitement over Christopher Walken on Twitter was quickly dashed. It’s apparently an “experiment” – and an old one at that – by Clusterflock.org. Dear Clusterflock: 1) Don’t toy with my complex Walken-related emotions and 2) Change your name. Immediately.

Apps on the Radar

–My good buddy Josh pointed me to Contxts.com, a why-didn’t-they-think-of-this-sooner technology. SMS business cards. Brilliant. Think of the trees, people, and sign up for this hugely simple service.

Tweet of the Week

–My new favorite Tweeter is Rob Corddry, who curses heavily and never fails to amuse.But his rant to his two-year old couldn’t match the sheer terror inspired by Jason Calacanis: “Just had lunch with the former head of the CIA. fascinating discussion about religion, nukes, the middle east, oil and electric cars.”

Where to start: How did faux-celebrity Calacanis wangle lunch with the former head of the CIA? Did he bring a hit list with him?  Can we get more details on the “nukes” part of this discussion? Will any of us ever sleep peacefully again? I need answers.
