I know I've been a fairly large fan of comments since the beginning.
I guess there was always some risk of trolls and flame wars, but with the 1 week delay on
original content, at least those of us with some level of commitment to the site manage to
have reasonable discussions on those articles before the wider audience arrives. In practice,
the signal to noise ratio has remained fairly high on all pretty much all comment threads I've
seen. This hasn't turned into Slashdot, or worse, FARK. :-)
