by Catharine P. Taylor , March 15, 2012 Among the things I didn’t do this week is avail myself of a homeless person ‘s hot spot. Primarily, this was because I didn’t go to SXSWi, but it’s also because the idea didn’t exactly go viral, though chatter about it certainly did. I’m not quite sure what BBH intended to get out of that whole gambit, but I do know this: The agency wasn’t expecting what it got.
