Welcome!
I don't like ever wearing shoes.
Have you tried out Vibrams? I have found them to be a delightful shoe replacement.
I am very unconfident in my skills at this point.
That feeling will fade as you read and do more. I do want to call back to something you said earlier, though:
I've always tried to be rational in an intuitive sort of way.
This is where you want to end up; it's one thing to talk a good game about biases, and another to understand them on the five second level. While reading through the sequences, it's helpful to try to turn the epiphanies into actions or reactions, rather than just abstract knowledge.
I did not think I was contributing anything positive to the world with my work.
If you are interested in putting your programming skills to work on rationality education, you might want to get to know some people at CFAR; there are a number of useful things that could exist but don't yet because no one has programmed them. (Here's an example of one of the useful things that does exist.)
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!
