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.

Haha! I don't think I'm worthy of squeeing, but thank you all the same.
In terms of the philosophy, I think that average utilitarianism is hopeless as a theory of population ethics. Consider the following case:
Population A: 1 person exists, with a life full of horrific suffering. Her utility is -100.
Population B: 100 billion people exist, each with lives full of horrific suffering. Each of their utility levels is -99.9
Average utilitarianism says that Population B is better than Population A. That definitely seems wrong to me: bringing into existence people whose lives aren't worth living just can't be a good thing.
That's not obvious to me. IMO, the reason why in the real world “bringing into existence people whose lives aren't worth living just can't be a good thing” is that they consume resources that other people could use instead; but if in the hypothetical you fix the utility of each person by hand, that doesn't apply to the hypothetical.
I haven't thought about these things that much, but my current position is that average utilitarianism is not actually absurd -- the absurd results of thought experiments are due to the fact that those thought experiments ignore the fact that people interact with each other.
