At SxSW 2007, the most talked-about (and criticized) new social web app was Twitter: a stream of random thoughtblurbs shared among friends and strangers, fed via IMs and text messages. Think of it as your syndicated consciousness (in 140 characters or less), predicated on the question “What are you doing?”

Everyone in attendance was perversely addicted to this little ajax-y creature, while at the same time grumbling about how there was no relevant way to leverage it in the marketing and branding worlds. Stephen Colbert is one of the best examples of good Twittering. We’re also fans of Fake Condi Rice. (Oh, and here’s my attempt.)

So we’ve gone from blogging (sharing thoughts from a desktop) to this mobile mini-blogging concept. How long before we’re able to subscribe to a person’s actual thoughts via RSS, generated and broadcasted from an implanted WiFi brain device?
