I think everybody is just saying that there's no need to be more rude than is necessary.
For example, when I "incorrectly" said that the D7000 doesn't have continuous autofocus, I was told "False. False. False.
The D7000 has continuous autofocus during video shooting..."
Not that this was a big deal, but the tone is pretty unnecessary. First of all, I didn't say 3 incorrect things, just one (which wasn't really even that incorrect. Nikon only claims to have continuous autofocus, but it's not like a video camera's autofocus at all).
Just saying, in the future it would be awesome to see replies like, "Actually, the D7000 does have continuous autofocus, even though it doesn't work very well at all."
I'm not really concerned about this for myself because I will admit that I came off as though I was very sure I knew what I was talking about, but more for people who might not really know what they're saying and are just repeating things they heard somewhere; I feel bad for kids who get wrecked in here for saying something wrong.
