It's kind of a way to keep track of what a network of people are up to. A lot of people use it for their friends, but even more use it for professional networks. I have a few computer science teachers and professional contacts who I can keep tabs on and if they are doing something cool that I might want to use I can get in touch with them. The character limit is to make sure it doesn't become a blog. You are just suppose to put quick updates on your activity.
