I saw a live stream of 500s presentations. There was a guy who couldn't stop swearing. I have nothing against swearing if there's good reason for it (eg. someone's really truly upset and needs to communicate how upset they are), but for a pitch to outsiders? It really bugged me. I guess for similar reasons, I love HN because it is really civil compared to other forums on the web; many other places (excluding quora), the trolls seem to run wild. I don't want to think all 500s participants are like that, but it rubbed me the wrong way. It seemed childish, like, "I'm cool because I can swear, check me out!" I don't think I should let it colour the way I think about all 500s participants, but for some reason, it's a permanent link in my mind whenever 500s is brought up.
