Perhaps the most significant challenge to the traditional peer-review practices comes from open-source projects like the Public Library of Science, which, though their journals are peer-reviewed, are available to all readers. Michael B. Eisen, an assistant biology professor at Berkeley and one of the co-founders (with Harold Varmus) of PloS, believes that academic bloggers face similar challenges to those of scientists who publish in open-source journals like his.
"One of the main issues we face in trying to convince junior academics to publish in PLoS instead of more established journals is their concern about how such publications will look at tenure time. I keep trying to convince people that, in an ideal world, tenure decisions should be made on the quality of one's work, not the venue of its publication. And there's no reason this shouldn't apply to things like blogs as well," he says.
Um, but the whole point of PLoS is (in their words):
The Public Library of Science (PLoS) was formed in 2000 by scientists and physicians to make peer-reviewed research freely accessible online to the world.So what does does this have to do with blogging? PLoS is a peer-reviewed journal that happens to have a different economic model behind it, and I presume should be treated like any other acadmic journal when it comes to assigning publishing credit. Blogging is not (in general) peer-reviewed or reviewd at all, which is why it's hard to account for it in tenure decisions. As far as I can see they have nothing to do with one another, other than both involving this new-fangled web thingy.
