This is something I don't get. They say that Twitter is now blocking embeds and I've seen an author respond by... including a screenshot of a tweet in their piece.
Except that's obviously better than embedding a tweet in the first place. It's better in every possible way. It's easier to write your article with an included image that you provide than to hotlink content from some other website. And when the tweet vanishes into the mists of history, your captured image of it will still be around, illustrating your article the way you were hoping the embedded tweet would do. There are so many articles out there with dead embedded tweets illustrating... something.
So, all that said... what was the effect that embeddability had on reporting? Why hasn't it been screenshots the whole time? What did easy embeddability enable that wasn't just as easy anyway?
