At first, I thought it was not for me because you could only write 140 characters at a time. I'm a long winded writer. You'd never know because of my short fragmented sentences, but I use a lot of them to get my point across. I started out putting my page on private because I didn't want anyone to know my business. I then found out that I was only tweeting to myself, LOL, no one else could read them. Whoops. After I set my page to public and found out how to search for my favorite celebs I was hooked.
I'm nosey. I enjoy reading what people are thinking at times. I also like the fact that not as many people have Twitter as facebook. It's better that way.
