The redesign of the PLoS journals today is not just a facelift. They continue to have fresh ideas and unconventional approaches. A recent email said that
we encourage authors who are fluent in languages other than English to submit translated versions of an article summary … in other languages. Translations should be submitted as Supporting Information files labeled “Translation of the article summary (or entire article) into language XXX by author YYY”.
That is a nice idea, showing another benefit of online journals, yea, yea.
