Now that Twitter has been popular for a year or two, I wanted some honest advice... Just curious - what has been the impact of Twitter on your life? Good or bad; please comment back... I've heard mixed reviews, but would be interested in this audience's opinion. One thought we've had is instead of doing a "personal" form of Twitter feed, have one based on our Rover or Spacecraft, and do Twitter updates from "its" perspective, rather than from a person's. What do you think about that? Would it be worth following if it's not an actual person? Thanks!
