Working as Community Manager for a company with millions of users is not a simple task. You need to walk the fine line of being overly professional and therefore boring, and on the flip side, too personal and amateurish. Richard Barley, the Community Manager of Tweetdeck does this perfectly. Anyone who has ever had a question about Tweetdeck knows they can ask him on Twitter and except a response within seconds. Richard keeps his audience interested and displays a high level of professionalism in his work.
