Open Knowledge Foundation in London (UCL) in the morning.
Oekonux in Manchester in the afternoon.
A little insane in terms of timing. There will be audio and probably video up as soon as possible after each talk.
One thing that I’m doing for a change is substantially talking without visual aids. I thought long and hard about this, and I’ve come to the conclusion that I need to face up to the challenge of holding an audience without lots of pretty pictures. Oratory, not entertainment.
