Here's another big art repository:

https://monoskop.org/Monoskop

And a very well-documented collection (a "wiki") of paintings, also non-profit:

https://wikiart.org

Another interesting one is Aaaaarg (according to Monoskop's wiki, originally with one less "a", acronym of Artists, Architects, and Activists Reading Group):

https://aaaaarg.fail/

https://monoskop.org/Aaaaarg

Basically it's a collaborative environment for reading, annotating and discussing texts. The content is submitted by users and (thus) of high quality.

I think you need an invite to access the community. Also, the domain used to be aaaaarg.org, but I think they faced copyright issues of some kind and had to find an alternative domain. (Not sure about this; excellent new suffix, though!)

EDIT: More precise description:

I’ve been listening to the BBC’s Introducing Mixtape podcast for a while. I also use Spotify and really enjoy its recommendation but the 6 Music podcast is just stellar.

As paywalls restore quality journalism, I believe a renaissance for curated content is possible.

As in, do you believe this uptick in quality journalism has already happened/is happening? And what associates it with paywalls? Presumably you'd have to be seeing quality journalism behind paywalls for this to be case?

Welp, apparently this is the rare case where ‘avant-garde’ isn't the same as ‘experimental’ or ‘underground.’
