Moments ago, our partner John Battelle and the team at Federated Media launched the beta of ExecTweets, a new service for folks to find and follow business execs on Twitter. It's an interesting model, essentially a lens on Twitter that's further organized by specific industry, like tech, media, healthcare, etc. While the content isn't necessarily up my alley, I can easily imagine a slew of other Twitter lenses I'd appreciate. I'd wager that ExecTweets is just a hint of what's to come. Congrats, JBat and FM!
