> But in many other fields there's a much greater need for expert curation and vetting. Let's remind something that is too often forgotten: peer review, while still useful, is NOT paid by the publisher. It is done for free by the peers. Yes, the publisher manages that and gets paid to organize it. The complex, high-educated job of peer-review is done for free, the automatizable, simple job of passing emails around is paid. Don't worry, I am sure we can find university staff or even a simple emailing script that can replace this function easily. I think that the reason it started with CS is much more mundane: computer scientists are much more likely to know that hosting a PDF is very easy and costs zero, and will probably be more confident in using tools like LaTeX.
