What I don't get so much is the push to take the result of a hackathon and turn it into a company. Several occasions I have seen investors promise to invest in winners, but most of the time it is just a group of people together for the weekend with already their startup or a dayjob. Lauch, Angelhack have this actually built in. Result: more focus on business and already existing teams (companies?) that come in together to use the event as a launching platform. Which is not the goal for me for a hackathon: trying out technologies, meeting new people, have fun. I already have my startup, don't need another.
