Hello everyone!
I run a midly successful meme page on Instagram, where they introduced an alt text feature a few months ago. I didn't want to use it at first, because I thought it wasn't necessary, but I realized that, what with the fact that I have over twelve thousand followers now, it might be a good idea.
The thing is, though: I don't post photos. I mainly just repost tumblr and twitter content, which is almost always in plain text and I don't know how best to describe it. I've taken to describing posts along the format of "tumblr post by" followed by a username and the text.
Is that enough, or am I missing things?
I know screen readers rely on punctuation and, the internet being what it is, the posts themselves usually don't have any. Would adding punctuation help make it more accessible?
Also, should I be using quotation marks (eg: post by username: "hello" with reply by username: "hello!") or does that make it more confusing?
