Your locality issue exactly mirrors my own. I know a great many people’s work through Twitter and blogs and other social media. But I do not know who’s doing what at my own college. When I get too upset about this, I remember that the reason I don’t know who’s doing what at my own college is because most of them aren’t using Twitter, blogs and other social media. A lot of them are on Facebook, but there tend to talk about the personal rather than the professional, so I still don’t know what they’re doing but I do know the names of their dogs.
