I'd come all the way from Paris, but probably not in August, which is all booked up as far as I'm concerned.
(Tip to event organizers: whatever date you currently think of as "comfortably far off" will come much sooner than you anticipated, and is probably too early for a non-trivial portion of your target market.)
I totally agree about timing! The reason for August is that there's a good deal on the venue, but if that's not viable I'm happy to go later. And if it is viable and successful I will likely be doing a similar event again.
On the principle of organising events that I want to attend myself, I would very much like to organise a rationality conference/convention in the UK. I organise events for a living; in addition, in my free time I've organised five ~200 person weekend conventions and several other events.
At the moment I am thinking of a one day event on a weekend or a Friday in August, at Stamford Bridge or somewhere else easy to get to around London. There would probably also be a pre-conference dinner, or private bar night with music.
Costs would be in the region of £50-£100 a head including lunch.
Can I get a show of hands to see if the idea is viable?
