this is really good. i didn't think much of filling out alt text because i figured, if you couldn't see the image, you're basically missing out anyways. but the perspective of filling out the alt text specifically to convey why you posted an image is good, i didn't consider that. so i'm glad i read this and broadened my horizon a little bit
i feel like it's still difficult to think of what to put for things like art i've done, but i'm gonna do my best to do give it a good effort next time
i think cohost has good support for adding alt text, but i realized i'm not actually sure. they call it "description", and i have no idea how well it plays with screen readers or if it actually functions as alt text
