I think journalist dont use blogs becouse there are better tools or journalist. In internet is a lot of webservices for citizen journalist, which can publish any kind of material without agreement of redactions.
for exammple: http://ohmynews.com/http://reporter.co.za/ or in Poland http://www.ithink.pl./
That kind of webpresence make Journalist more independent in readers eyes.
