Regards from Argentina,
Great post. I had started reading through this site randomly while I got more and more into HPMOR, which a friend recommended, and having a little list of posts to start will most probably prove helpful.
I would like to mention that the thing about this community I found the most astonishing was a comment that read something like "Edit: After reading some responses I've changed my mind and this comment no longer respresents my beliefs." I did not even know that it was possible for a human being to be so greatful and humble upon being proven wrong. And humility is something I most definitely need to learn, and I suspect I will be able to do so here. In fact, I already did, for I acknowledged the fact that someone outside my field (pure math, until recently) has something to teach me. Yes, I am (was?) THAT arrogant in a deep level, but here and now I just feel like a child, craving to learn the art of rationality.
Thank you all for what this site constitutes!
To me it feels easier to admit mistakes in an environment which does not punish admitting mistakes by loss of status. Where people cooperate to find the truth, instead of competing for image of infallibility.
Just saying that how one reacts on being shown errors is partially a function of their personality, but also partially a function of their environment. Changing the environment can help, although sometimes bad habits remain.
A few notes about the site mechanics
A few notes about the community
If English is not your first language, don't let that make you afraid to post or comment. You can get English help on Discussion- or Main-level posts by sending a PM to one of the following users (use the "send message" link on the upper right of their user page). Either put the text of the post in the PM, or just say that you'd like English help and you'll get a response with an email address.

A note for theists: you will find the Less Wrong community to be predominantly atheist, though not completely so, and most of us are genuinely respectful of religious people who keep the usual community norms. It's worth saying that we might think religion is off-topic in some places where you think it's on-topic, so be thoughtful about where and how you start explicitly talking about it; some of us are happy to talk about religion, some of us aren't interested. Bear in mind that many of us really, truly have given full consideration to theistic claims and found them to be false, so starting with the most common arguments is pretty likely just to annoy people. Anyhow, it's absolutely OK to mention that you're religious in your welcome post and to invite a discussion there.
A list of some posts that are pretty awesome
I recommend the major sequences to everybody, but I realize how daunting they look at first. So for purposes of immediate gratification, the following posts are particularly interesting/illuminating/provocative and don't require any previous reading:
More suggestions are welcome! Or just check out the top-rated posts from the history of Less Wrong. Most posts at +50 or more are well worth your time.
Welcome to Less Wrong, and we look forward to hearing from you throughout the site!
Once a post gets over 500 comments, the site stops showing them all by default. If this post has 500 comments and you have 20 karma, please do start the next welcome post; a new post is a good perennial way to encourage newcomers and lurkers to introduce themselves. (Step-by-step, foolproof instructions here; takes <180seconds.)
If there's anything I should add or update on this post (especially broken links), please send me a private message—I may not notice a comment on the post.
Finally, a big thank you to everyone that helped write this post via its predecessors!
