Wasn't really a hackathon but it fits into it (I guess). This year's WCEU had a full day for working on WordPress stuff. I was really looking forward to it but when I was there the people just used this to communicate with the original extension developers about their specific code problems at their companies and I was just like what the fuck? I then joined a team who wanted to do something they needed for a specific case and requested that code to be merged to the plugin. When I tried to give some input they just were like yeah ok and ignored it.
