If you are getting into twitter for the first time, much of the lingo, techniques, and characteristics of a good twitter account are hard to keep up with at first. Take it easy. Don't lose any sleep over this. Just open up a new account and follow along with some tweets you might be interested. You might not send out your first tweet for a month or more. That's ok! Plenty of people are twitter followers alone and never tweet at all. I bet they still find it valuable nonetheless...
