Academics, I beg you. Please put copies of your published papers on your website, arxiv, whatever. Not only because it's great for the broader world beyond academia (who can't get behind paywalls at all) but it just took me 15 minutes to try to figure out how to log in to some particular database to get a copy of a paper. I don't even like the 3 minutes it takes to log into the ACM DL versus copying a title into google. Follow copyright rules but you can almost always post SOMETHING somewhere.
