One of the key things to do early on is to work out what your goal is. It could take a little while to work this out but the sooner you nail down what you’re going to use twitter for the better. There’s no right or wrong with how to use Twitter - your focus might be:

* to use it on a personal level to share what you’re doing with real life friends and family
* to build up you and your blog’s profile in your niche
* to unwind and have fun with new friends
* to build up your network in a niche

The list could go on (and it could include multiple goals) - however knowing them up front will help you as you explore how to use it.
