Wow, just done my first flying solo Barcamp session, and I'm relatively please with how it went. It was a pretty loose exploration of the last BBC Micro (late 80's, hugely influencial, but with a gestation and reasoning behind it which might not agree with your preconceptions!), and an exploration of whether and what the BBC could or ought to do along the same lines some 25 years later.
Thanks a gazzilion to Rain for blogging it. That's actually rather more structured and complete than anything I had written down about it!
I'd also like to thank the audience, who not only seemed really attentive, but at the end everyone engaged in a really spirited discussion of the potential avanues in which this could develop. I hope to continue this dialogue in Backstage, keep eyes peeled for a blog post there.
