Did I believe that before I asked the question? No, I wouldn't say so...
Why not? Perhaps you could spell out the Socratic case a little more? I'm not stuck on saying that this or that must be what constitutes belief, but I do have the sense that I believe vastly more than what I do (or even am able to) call up in a given moment. This is why I'm reluctant to call explicit awareness* a criterion of belief. On the other hand, I'm not logically omniscient, so I can't be said to believe everything that follows from what I'm explicitly aware that I believe. My guess as to a solution is that I believe (at least) everything that follows from what I explicitly believe, where those implications are cases of implications I am explicitly aware of.
So for example, I am explicitly aware that the car weighs more than 100kg, and I'm explicitly aware that it follows from this that the car weighs more than 99kg, and more than everything between 99 and 100kg, and that it follows from this that it weighs more than 99.1234...kg. Hence, infinite beliefs.
*Edit: explicit awareness should be glossed: I mean by this the relation I stand to a claim after you've asked me a question and I've given you that claim as an answer. I'm not sure what this involves, but 'explicit awareness' seems to describe it pretty well.
I'm not sure I have anything more to say; this feels more like a question of semantic preferences than anything deep. That is, I don't think we disagree about what my brain is doing, merely what words to assign to what my brain is doing.
I certainly agree that I have many more things-I-would-label-beliefs than I am consciously aware of at any given moment. But I still wouldn't call "my car weighs more than 12.141341 kg" one of those beliefs. Nor would I say that I was explicitly aware that it followed from "car > 100kg" that "car > 12.141341 kg" prior to explicitly thinking about it.
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!
