@blatham,
in my areas of deeper interest eg, for every Nicholas Wade, Neil Shubin or Greg Sergeant, there lie a dozen or more "second level" bloggers who gain as much a following (albeit more locally) as do the principles. For example, a Nick Wade, Paul Krugman or David Quammen, writing as first level workers in politics, econ or science or genetics and engaged in their own blogs (often its required by their news corp contract),
the second levels of bloggers on the other hand , like rumors are passed from kid to kid, will morph when the bloggers add their own ( much less studied and often silly) views that many readers arent sophisticated enough to draw valid concluions.
I never gave the point that Set made any thought, but think about it, as Krugman posts more extended versions of his NYT econ columns, sometimes his opinions very quickly get picked up in the "capitol blogs", and are generously expanded with stuff that is often a pile of dogshit.(But , like dogshit, its crapped out at a lightning fast rate, much quicker than Krugman rote the original)
I know several writers who are "old time" REAL journalists whove been picked up and pub'ed by The Atlantic. These folks may work months on an article that may become nearly OOD by the time the mag prints it. Yet, in a short weekend, some wag with a blog will post chunks of the well researched article and "dress it up" with total crapolla.Yet they are all considered to be "journalists". Hence the entire profession is besmerched by too many lazy second level bloggers. I think the bloggers who are first level (by past chops earned for their work in investigative reporting in politics, econ, history, or science reporting). The READRS, unless they are expert themselves merely pick up "sound bites" of the chaff as qwell as the grain.
However, many of these 1st level reporters are more appreciated, and much better paid to write researched books in "Creative non-fiction" (But even they get ripped off by hasty bloggers who take facts from a reporter/writer's (like a Mark Bowden )work and write junk blogs )
Look, in my subject, Im a mile high but an inch wide, so, in areas that I hve no pwrsonal tudied knowledge I will more often or not BELIEVE what some of these bloggers (from my local Lancaster/Harrisburg/Philly metro blogs) say. Only if I read the original authors on a subject am I able to really sort out some truth. But thats often the art of picking fly-**** from pepper.
I guess Im like Set on that point, I more and more, stay away from blogs that vaunt self proclaimed "expertise" . I do visit hobby ,garden, cooking, trout fishing, and wooden boat blogs. What the hell can possibly go wrong with getting some bad woodworking plans? You soon discover that the author had his head up his ass when the boaqrds dont meet.
