I've recently started following https://www.instagram.com/insta_repeat/
The point of the account is (I think) how conformist Instagram makes us, aesthetically. Which, hey, guilty as charged y'all! I have so many dutch angle shots of homemade bread on my feed it's a travesty.
But what also struck me is how back in my art school days this would have been a whole thesis that culminated in like a gallery exhibit (this was pre-Instagram of course) and that led to the revelation that Instagram is to gallery art photography what Twitter is to stand up.
