The AP and RP bebo sites.. a weird stew of personal and professional. And it's hard to figure how much each is meant to be an individual or the institution.
I guess this is what Evans means by "the special kind of sophistication" necessary in "an environment that, while ideal for information exchange, is designed for casual interaction."
KaleidoscopicWorld points up the same tensions with lots of curly questions, trying to get at the right balance.
To me it seems social network websites are better suited to individuals. If an institution has two or three or more librarians involved they could set up separately, but still be well and obviously linked. Their interactions would be transparent and part of the thing that draws others in, drives the "net-working," and spins the wheel on the tail of the donkey right between the eyes. So to speak.
Whatever, Evans is right with the "paralysis by analysis."
