I think Smartaz accidentally showed the difference between the majority of blogger (on this site) and journalists. Most of the folks here desperately crave feedback even if it is critical while journalists have become very used to ignoring criticism of their work by anyone other than their peers. Check out Noam Chomsky's blog if you really want to see how paranoid these folks are about hearing how the public feels about their stuff. He only started "allowing" coment after a large hue and cry was set up over the lack thereof. Even now it is a restricted audience.
Of course they are perfectly within thier rights to feel this way and I mean no disrespect to Smartaz by pointing this attitudinal difference. (I have read his reasoning behind disallowing commentary and can see some very salient points) but I bring it up simply to highlight the difference between conventional journalists and bloggers.
