I've tried to compare it more accurately.
It's very hard to evaluate selectivity. It's not just the raw number of people participating. It seems that large majority of serious ACM ICPC participants (both contestants and their coaches) are practising on Topcoder, and for the ICPC the best college CS students are recruited much the same as best highschool math students for IMO.
I don't know if Linus Torvalds would necessarily do great on this sort of thing - his talents are primarily within software design, and his persistence as the unifying force behind Linux. (And are you sure you'd recruit a 22 years old Linus Torvalds who just started writing a Unix clone?). It's also the case that 'programming contest' is a bit of misnomer - the winning is primarily about applied mathematics - just as 'computer science' is a misnomer.
In any case, its highly dubious that understanding of QM sequence is as selective as any contest. I get it fully that Copenhagen is clunky whereas MWI doesn't have the collapse, and that collapse fits in very badly. That's not at all the issue. However badly something fits, you can only throw it away when you figured out how to do without it. Also, commonly, the wavefunction, the collapse, and other internals, are seen as mechanisms of prediction which may, or may not, have anything to do with "how universe does it" (even if the question of "how universe does it" is meaningful, it may still be the case that internals of the theory have nothing to do with that, as the internals are massively based upon our convenience). And worse still, MWI is in many very important ways lacking.
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!
