I agree with Atrios that the kids are alright, but I don't think the anger he mentions here is new. I think that it is just more easily dispersed via the internet. The vitriol you read in most comments sections today was always there, but pre-internet it was someone reading the paper and yelling at the wind (and maybe his wife and kids...and yes, it was probably a "he" then just as now).
The internet is a remarkable force in our lives, and primarily (overwhelmingly?) for good, but it is a tool, and one that can be and is used for ill at times.
