I don’t think I have an unmet need to interact with random unknown people. After all, Josh Miller is not screening out the uncool, so after the surge of the glitterati it will be simply random people, even if they are the next door neighbor of somehow I vaguely know. My real need is to gather information that is critical to my ongoing research practice, ie living on earth in the present day. And as a side effect of that, I have been meeting really cool people already, in the normal course of events. They are my Twitter contacts, or the folks I follow on Tumblr. Potluck has it backward.
