people love a train wreck, + it has the lesson of being careful of who to pick for your cofounder, and about giving second chances to people who screw you over.
I'd like to believe that this site is better than that – that it's not about watching train wrecks. The problem with picking co-founders isn't that people don't know it's important – it's that they ignore it anyway or don't know how to tell. It's about as useful as a surgeon general's warning on cigarettes.
