The link's in my profile, but in a nutshell: it's taking the stamps of approval peer reviewers currently give, and removing the journal as its intermediary. So when researchers read an article that is not published in the traditional outlets (e.g. on a preprint server like arXiv), and they find that that article is up to scientific standards, they can publicly endorse that article right there to inform other potential readers and funders of that.

It's still early days and we're still testing the concept, but I think there's potential. I've got a newsletter that I haven't sent a mail to for a while, but if you're interested I'll eventually send an update there when there's more to share: https://tinyletter.com/Flockademic
