For instance, I post links to phys.org a lot more and I'm less likely to post a link to the paper because (1) Mastodon can't extract images out of the latter and (2) I get more replies like "this is over my head" from Mastodonsters whereas I think most of you might think you'd look stupid if you said something like that. On the other hand I rarely post links to The Guardian to Mastodon because it can't extract images from Guardian articles.
Bonus: if you look right now you'll see the user interface that I use to post to HN! [1]
