Tweet, Tweet...

I just set up a Twitter account. As I was "tweeting" my first few chirps, I started to wonder what the purpose of it was. What makes Twitter so much different than Facebook?(besides the pictures) Is it better? It is slightly less time consuming, which with 3 children, homeschooling, an Etsy business and life, is a perk. Nothing sucks up my non-existent time like social networking, but it is STILL just another way to chat. I think I'll try it out for awhile and see if it is worth the effort vs. a little more time to run my life.
