S/N on comments goes down as soon as the thing becomes popular, am insightful comment is as likely to appear on slashdot, on a wordpress install or on TC, if it's n a popular topic.

And no blogger can reasonably write often enough on an array of subjects wide enough to keep the level of a news site, unless she takes in some other authors, and at that point there is not a lot of difference.

Also, there are still many sites that are widely above 90% of the blogs, such as ARS o the reg.

There are many interesting tech blogs (acangiano's is one :) ) but they don't fill everything that tech journalism should be.
