Today I set up my first group on Facebook, and did a little searching around. Though I am somewhat of a pundit/expert on social software, I admit that I use the major sites very little. Part of this is due to my "old school" habits of running my own servers. Since I have my own domains, can do ftp, setup and admin a cms, why would I want to use something else?
Of course the answer is that "everyone else is doing it." And there is something to be said for the access to others, and the ability to get message out and share content effectively. I certainly have utilized youtube quite a bit, but Facebook and LinkedIn have been somewhat on the back-burner for me personally.
Today's foray into Facebook was business related. We have a summer intern program and the idea is to provide a space for them to keep in-touch with the institute. I immediately defaulted to, "we can set up a site..." but why not leverage existing networks? That then leads to some searches on Facebook, and who can't resist looking up old friends and/or ex, um, friends.
