BarCampSeattle is an ad-hoc gathering born from the desire for people to share and learn in an open environment. It is an intense event with discussions, demos, and interaction from attendees. It is an international network of user generated non-traditional social conferences: open, participatory workshop-events, whose content is provided by participants, often focusing on early-stage web applications, and related open source technologies, social protocols, and open data formats. Oh and super fun!!
I will be going to this on Saturday to see how this type of event works. I always enjoy going to these types of things just for the networking opportunities.
