@pfefferle OK the .bin thing seemed to be an artifact of the mobile I was using when replying to you with the previous comment (I was using Tusky, clicked on the link, which opened Firefox, which did the weird .bin download thing). On the PWA, the blog page opens correctly, but shows the HTML tags for the mentions. I have another account on fediscience.org and there it shows correctly, so this may be an issue with the HTML scrub on sociale.network
Ping @gubi who is an admin here.
