Thing #3

Adding a friend is easy to do. Searching is also easy in Facebook. I am sure this could also become addicting if you have the time.
The anonimity of the social networking makes it easy and fun for poeple to be whomever they want to be. I imagine you can communicate with many people at one time which could be fun and helpful.
I am somewhat familiar with social networking. There was nothing really surprising.
I suppose dissemination of information could be helpful by using the social network, but other than that I do not see real uses for it.
