The next LW London meetup will be on September 14th. Join us from 2pm to talk about the sorts of things that your other friends will look funny at you for talking about.
I'll try to remember to bring an identifying sign, but if you have difficulty finding us, my number is 07792009646.
About London LessWrong:
We run this meetup approximately every other week; these days we tend to get in the region of 5-15 people in attendance. By default, meetups are just unstructured social discussion about whatever strikes our fancy: books we're reading, recent posts on LW/related blogs, logic puzzles, toilet usage statistics....
Sometimes we play The Resistance or other games. We usually finish around 7pm, give or take an hour, but people arrive and leave whenever suits them.
Related discussion happens on both our google group and our facebook group.
