If I had a "sweeping claim" to discuss, how should I have posted it?
See "give more explanations and context". If you're concerned with "never find a practical way", that's an entirely different discussion than "isn't Turing-computable" (in this community, if something has a strictly technical interpretation, that's what is defaulted to). Give enough context so that a reader knows what you're concerned with (practical applications, apparently, see I wasn't aware of that), instead of a somewhat theoretical sounding claim (which you apparently meant in a more practical way) with a proof that turns out to be wrong, given that strictly theoretical claim. Also, I was only pointing out shortcomings of your proof, to do so no stance regarding Turing computability is required. However, there is no reason to assume that superdeterminism would require incomputability, on the contrary, as long as the true determinist laws of physics are computable, the universe would be as well, no?
As an aside, would I in general be expected to read all 300+ comments on a post before commenting?
Well, at least the top level comments with a couple of upvotes, so you don't repeat one of the main responses? That boils it down to 35-ish comments.
Oh. I need to be "strictly technical"? I'll go back to the one about Turing computability and edit it to reflect a "strictly technical" comment.
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!
