HI Gust,
I've tried this before: http://lesswrong.com/lw/64h/checking_for_threshold_number_of_rationalists_in/ besides Us, there is only one user, dyokomizo that is from são paulo that I know of.
Anyway, Hi! Always good to know we are not the only ones. The best place would be Starbucks near avenida paulista, in Campinas com Santos. But sincerely, I don't think we should meet before there is 5 of us.
You may be interested to know that given this absurd lack of less wrongers in são paulo, I decided to start an institution, pretty similar in interest to Leverage, and a little less with singinst. There are about 10 of us now, and a Lot of stuff to do to effectively improve the world (including rationality training).
I'm writing from Albert account, I'm his brother. I'm living in São Paulo and will probably be there!

WHEN: 14 March 2012 07:00:00PM (-0300)
WHERE: 1034 Alameda Santos, São Paulo, Brasil
I have no idea whether there are people in the area, but I guess it's worth a shot. In this first meetup I hope we can get know each other and plan the next ones.
I'm still thinking about a good place to do this, please offer any ideas you have. Somewhere near a Metro station would be great (maybe near Avenida Paulista?).
If you think another date and/or time would be better, say it in a comment. And PLEASE comment here if you live nearby, even if you can't show up!
EDIT: Meeting point: the Starbucks at Alameda Santos with Alameda Campinas.
