Good Definition for Twitter

I found this definition of Twitter from the International Children's MinistryInsight E-Mag - August 2009. Ryan Frank, Children's Pastor at Liberty Baptist Church in Sweetser, Indiana explained it this way:

Twitter is a free social networking and micro-blogging service (no, I didn’t use those terms with the grandparents). Here’s how I explained it to them. Instead of sending a dozen e-mails or text messages, you send one message to your Twitter account, and it goes to all your friends (or followers). You could also explain it as a service that functions like a giant bulletin board where anyone can stick a short note.
