Looks like the big news of the DNC isn’t Obama or Clinton, but the unveiling of formerly-pseudonymous liberal uberblogger Atrios as Bryn Mawr econ prof Duncan Black.  I’ll confess, I’d (perhaps rather unsportingly) IP-traced him to Bryn Mawr a while back and spent some time thumbing through faculty profiles trying to divine who he might be; Duncan Black wasn’t even on my list of guesses.  Though I’ll note there’s minor irony in his sharing a name with a seminal figure in the development of public choice theory.
