Plugin for Oauth-based comments
I've started using Koken to replace google photos and a couple other self-hosted photo galleries. One BIG advantage of Google Photos is how easy it is for my viewers to add comments.
I know there's the disqus plugin - but my audience isn't going to sign up for that. But, they all either have Google or Facebook accounts.
So: could a comment system that authenticates against Google/Facebook be created? I'd buy it!
