I find it hard to compare both sites, the scopes are quite different and so their users, although I believe many people answering questions here also use SO as a source for their knowledge. While the majority of the questions here is practical, SO is more theoretical, I feel.
In my experience, the average level on both questions and answers is high(er) on SO. Looking at both sites' numbers, your (or my) questions are more likely to be a dupe, and will not be valued "to the top" easily, which might be experienced as less friendly.
Having said that, I quite disagree with you that questions are received "more friendly" here. Just look at the downvotes programming questions offenoften get, or questions accidentally posted on the wrong site for example. The only possible motivation to downvote in such cases is to express it isOP did a "bad thing"; such a question will be closed as off topic anyway, with or without downvotes.
So, although I can see big differences on both sites, I don't really share your experience that "we" are much more friendly here. Maybe a few examples would make me think differently :)
