I'm not communicating enough about the https://artfeed.org project, and as a result there aren't many registrations. So I've done away with the invitation system and opened up the site to everyone.

Artfeed is a simple way to follow the work of photographers and artists via their #rss feeds, with an interface dedicated to images.

You can also add your own #feed to the site and create your profile, like mine here: https://artfeed.org/@atlza
A great way to share your images and likes!
