I'll checkout stirplate.io, but just wanted to point out that there has been a mandate on the books for years now that if you get funding from a federal agency (that does a significant amount of research funding), you have to deposit that article in a public archive, usually Pubmed Central or an institutional repository.

The NIH now requires you to include the PMC ID number on any reference you cite in a grant, so they're more or less forcing people to comply, after years of asking, pleading, and begging.
