Mr. Tweet will do some homework for you - although I still believe in the randomness and greatness of building a network - I often find people that I thought I was following and wasn't. I don't know how this will work, but am goign to test it out!
Nice post. I think many of us are wanting to push past the cool and trivial and use Web 2.0 to do meaningful, authentic things (imagine how students feel.)
I think a more important question is that "Are students bored with worksheets?" Authentic and network building experiences and learning should become part of what they do. They don't want the trivial any more than we do.
