This may be a bit chatty for the "new PSJR" but indulge me. After receiving a rejection from a higher-ranked journal, a coauthor recently suggested that we publish in an online-only journal which focuses on precisely the research we do. Other than being online only, the journal is just as good as any other, peer-reviewed and all of that, and yet, as soon as learned that this journal doesn't come out on paper, I immediately thought to myself "No way in hell. Next he'll be suggesting that we publish in a journal of undergrad research." This seems irrational, but I think a lot of people probably feel the same way.
So that brings me to my questions. Why do we look down on online-only journals, and why do journals come out on paper at all? Personally, other than flipping (and I mean flipping) through the APSR, I do all my reading online - or via PDFs that I print out from the internet. So, why do journals spend an incredible amount of money to put out the articles on dead trees? Why don't they all just go online?
