As almost every participant I believe, my opinion is that the lightning talks were a great idea in the first place, and also a great success.
At the very last minute, I changed my mind about the contents. I got a bit bored with too much Lisp technical stuff and decided I would talk about Lisp, Jazz and Aïkido for a change (see the corresponding Sci-Blog entry
). Some people did like the idea and I got several very interesting conversations after that. It's always cool to meet other lispers that are musicians as well, and even martial arts practitioners !
I'll keep the Clon stuff for the European Lisp Workshop
instead, and I think I will give a tutorial on it there.
