OK I've actually been back several days now, just hadn't got around to posting this. Read my Raincity blog post on DrupalCon Szeged here. In short, it was mind-blowingly awesome. I have to say the social aspect was really fantastic - I got to meet so many fascinatingly interesting people. Drupalers really are an unusually diverse bunch of people with all sorts of different backgrounds. The sessions I attended were all excellent.
