I'd agree with James, that the live demo didn't really add much. Personally I'd have liked to see a bit if discussion on /why/ something was slow in mysql and what properties of a nosql makes a nosql database able to do the same query much faster. That would make it easier to relate you examples back to problems we may be having and be able to decide if nosql is an appropriate solution.
Good talk and a good introduction to the topic. Might have been a bit mathsy for first thing in the morning, but that isn't the speaker's fault. A tip for any conferences using this talk in the future: put it after the morning coffee break!
This talk gave a good presentation of PHP history and reminded us just how many sites rely on PHP but I felt there was quite a bit missing from the what would the world be like without PHP side of the talk.
I wonder if the talk would be better if generalised to 'A world without open source', this topic may enable a better contrast and provide a more inspirational talk for a keynote.
I found this entertaining, but it did unfortunately miss out some of my favourite python sketches.
Overall, I think a little bit more focus on the message between the clips would make this more universally appreciated.
