I was present for the Startup School Europe in London this year, and I have to admit I agree with Colin. Perhaps Startup School SF is a little different, but Startup School in London seemed more like a sales pitch for Y-combinator (not in itself a bad thing). The speakers were interesting for sure, but did little to add value for budding, first time entrepreneurs. I hasten to add however, that the networking was great and my personal disappointment was perhaps more due to "misaligned expectations".
