I am just beginning to realize the value of social networks.
Currently I use Facebook to stay in touch with friends and LinkedIn as a professional network.
I have used other web 2.0 tools such as wikis to work with campus groups and our department on specific projects in the past. I have created forums within wikis for team correspondence.
Now I can see now that there is much more value in creating more specific networks to reach out to a larger pool of folks with similar interests. A group of innovators who experiment with educational technology could share details about success with certain applications.
