I guess this was kind of inevitable, but it feels like the end of an era.
I follow some photographers who use workarounds to letterbox the photos they post into the aspect ratios that they desire. Which isn't ideal for them as the poster, or for me as a consumer. In that sense, I guess this is a kind of a Desire Path update.
