Earlier this week I kicked off Italian Graffiti Factory, which is an overly-pretentious name for a site that is focused on bringing together co-founders and helping them to get and stay motivated. For the alpha stage, the site is going to be very specifically focused on helping co-founders to come together to build a prototype and submit a killer application for YC Winter 2010.
