I love the web. The web should allow anyone to access any experience that they need without the need for native install or content walled garden.
I've run hackathons and learned they're not for winning customers. They're not about startups or brand awareness. They're about learning and improving your product. Treat them like beta tests where developers help find bugs and make your platform better. Focus on making your platform valuable and easy to integrate with. Reward developers for providing feedback, not just cool demos.
I had a great time speaking at the Berlin GTUG, despite the unexpectedly hot weather. I presented on Web Apps, highlighting the differences between native and web apps, key principles of good app design, and some of the exciting new possibilities with HTML5, CSS3, and WebSockets. I wish I'd had more time to delve into frameworks for building great apps and do some live coding. Chris Chabot also gave a fantastic talk about Buzz. The venue, BetaHaus, was excellent, and I was impressed by everyone's English fluency. Thanks to all who attended!
