Some had to try auctioning a Twitter account.
Fun experiment and the results will be informative.
Update : StoweBoyd doesn't actually think that much of the idea. Seems to think that all the value of a twitter account is in the individual, not the collection of followers.
But I wonder if there might be an intermediete position. What if some online personalities could be more like fictional characters : the architypes here might be James Bond or Dr. Who.
Different actors play the roles but we have models and standards to compare them to. We wonder quite obsessively what the new Bond will be like. Will he be as good as the old? Will he be as "Bond" as the old.
I once read that Robert X. Cringely was not the original but a substitute who took over the original column. Whether this is a myth or not, it seems that new writers could take over an existing role, if they perform it well enough.
Might we be asking ourselves "who'll be the next Scoble?" Unlikely. But Shel Israel already seems to be moving in the direction of a fictional character.
