This falls uneasily between two stools for me. For a photography-focused space, it doesn't have anything like the wealth of photography tools and data that Flickr does (or even just EXIF). For a community space, it doesn't have bookmarking or nudging or sufficient interaction beyond comments to make that work for me either.
Both those things can be secondary if it's exposing you to great new work and new trends in photography, but the onboarding didn't bode well on that front: of all the photographers it suggested I follow there was one woman and one non-white person in the mix. That's not a slam dunk on their work but it did turn out (from what I can see) to all be in a very similar sort of "late-millennial white man with a mirrorless" niche.
