I'd definitely go, unless it was on the weekend of the 9th Aug.
I would probably be happy to let some people stay at my house if they were traveling from outside of London. I would have to agree this part with my housemate.
It might also be worth adding to this thread on the LessWrongLondon group https://groups.google.com/forum/?fromgroups=#!topic/lesswronglondon/sLdnshaeHHg (I would certainly appreciate it as I don't check LessWrrong.com very often)
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?
