Mensa

I scored high enough on an official IQ test (as in, from a clinical psychologist who tested me professionally in person, not some illegitimate online test) to get accepted into Mensa. Should I do it? Some people love it, others claim that it's just a bunch of pretentious cunts playing board games and bragging about how smart they are. What do you think? What have your experiences in Mensa been like?

Being smart autists, I figure that at least some of you might know what Mensa is like. I would appreciate any and all serious insight.

Here's a useful table (sigma=15):

IQ                  Ideal group of peers
<55                 Euthanasia facility–beast-like, unable to cope with any form of societal structure or logic.
55–70               Zoo, chimpanzee community—severely retarded with primitive social tendencies; able to use tools.
70–85               Worship place—unable to reason without external influences but highly social; capable of the rudiments of abstraction.
85–115              Facebook, twitter, digg, reddit—majority of the world's population... Able to gain from the experience of others. Mild abstraction abilities.
115–130             Hacker News, Mensa, /prog/, Stack Overflow—sharing knowledge and ridiculing lesser lifeforms gives an inflated sense of satisfaction that helps to cope with the ability to ask interesting questions and the inability to answer them.
130—145             Academia. Most proficient scientists fall here.
160–175             Mega, Glia, Pi and other High IQ Societies—Highly intelligent, capable of profound abstraction and with a knack to solve difficult puzzles as an act of mental masturbation; usually polyglots, and polymaths.
>175                Seclusion—most peers would give the intellectual satisfaction of a pet.

IQ                  Ideal group of peers
>115                People who can use bbcode-tags

I was invited to join but seriously ...

Who wants to listen to a bunch of fucking neckbeards whine about their lack of social graces.

The other favorite topic for whining is how People Like Us should be in charge since we know so much better. Instead of cleaning toilets on the night shift, even.
