I made an account seven months ago, but I wasn't aware of the last welcome thread, so I guess I'll post on this one.
I'm not sure when I exactly "joined". My first contact with this community was passing familiarity with "Overcoming bias" as one of the blogs which sometimes got linked in the blogosphere I frequented in high school. As typical of my surfing habits in those days, I spent one or two sessions reading it for hours and then promptly forgot about all it. Second contact was a recommendation from another user on reddit to Lesswrong. Third contact was a few months later when my roommate recommended I read hpmor. I lurked for a short time, and made an account, and went to my first few meetups about two months ago. Meetups are fun, you meet lots of smart people, and I highly recommend it.
First impressions? I think this is the (for lack of a better word) most intellectual internet community that I am familiar with. Almost every post or comment is worth reading, and the site has got an addictive reddit-ish feel about it (which hampers my productivity somewhat, but que sera, sera.)
I've noticed that most of the opinions here tend to align precisely with my own, which is gratifying, because it's evidence that my thinking makes sense. However, it's also irritating, because it means I learn less and I have little to contribute. It's a little disconcerting for someone who thrives on discussion and is usually forced to play the role of the contrarian. Not that I'm complaining - it would be quite worrying if rationalists didn't tend to agree. Plus, it's really refreshing to have discussions where two people mutually try to figure out where the truth lies, rather than arguments where two people try to convince each other of something.
Biggest upside: Lesswrong has it's own, rationality/philosophy specific jargon, which is really helpful for communicating complicated ideas using very few words. In addition to introducing me to a few concepts I'd never even considered, I think the greatest benefit I got from reading this site is that I've got a better language to verbalize abstract concepts.
What I'd like to see: Expansion from the philosophical side into practical things, like scientific knowledge,, useful skills, etc. It's not often you get a community hub with such a high concentration of skills and knowledge, and I think it should be put to more use. (the rationalist-utilitarian charities lesswrong is loosely affiliated with is one good example of this being done successfully)

I noticed this as well, while first reading the sequences. I flew through blog posts, absorbing it all in, since it all either matched my own thoughts, or were so similar that it hardly took effort to comprehend. But I struggled to find anything original to say, which was part of why I initially didn't bother m...

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!
