Jessica - You can use Twitter for whatever purpose you wish. Some interact with friends, some post interesting/helpful article links, some talk about how their day is going, some use it for marketing, or announcements, or events ... the list goes on & on.

You can think of it like a big ongoing party, where you dip in and out of the conversation.

Of course, if your tweets are good, you'll attract more followers; but you don't have to focus on quantity of followers - you may choose to focus on quality instead.

Just jump in there and give it a go. You'll get the hang of it.
