The Northwest's newsrooms, taken wholly, are fitfully represented in the blogosphere, but the editorial pages do seem to be moving a bit ahead.
The latest to run this route is Spokane Spokesman Review, which this month started the Matter of Opinion blog fed by members of the editorial page staff (which can include the paper's editor and publisher). Two of them additionally have blogs of their own (D.F. Oliveria's Huckleberries Online being a very regular stop for us).
Neither the Seattle Times nor Post Intelligencer, both of which run a number of blogs (including a good political blog by each), seems to have an editorial page blog, although the Tacoma News Tribune has one. And there's an editor's blog at the Yakima Herald-Republic.
The Portland Oregonian has had one too for some time now. The Salem Statesman Journal has an editor's blog, as does the Medford Mail Tribune, but the Eugene Register Guard doesn't.
We found interesting that the first blog (that we know of) emanating from the Boise Idaho Statesman was by the paper's editorial page editor, Kevin Richert. (It too is a frequent stop.) Not many others so far in Idaho, though. Opinion pieces often do show up on the Idaho State Journal politics blog. There are some preliminary blogging efforts at the revamped Lewiston Tribune web site. The only public blog at the Idaho Falls Post Register has to do with its new press.
Our guess is that a couple of years from now, there will be more.
