1.)Yes! I think twitter is pretty cool site with lots to do. It seems like you can keep up with you loved ones more frequent.
2.)I could use it to keep in touch with people that I work with or want to work with. This could aslo be good for your boss to post a little upddate in what would be going on at work that day.
3.)A bussiness might use twitter to get advertisment. They could also use it to tell people about some of the new and improved things that may have occured. Last, but not least they could get peoples advise on this website. They could tweet on how they think their bussiness should improve or get better!
