Some Twitter users will take umbrage to this recommendation, but before you launch into Twitter, take some time to think about how you’ll use it and who you’re going to be on the service. Some will tell you to “just be yourself”—and you should certainly bring your personality to Twitter—but you must consider who will be following you and what impression you wish to leave.
