@johncarlosbaez I didn't see this either - it seems somehow my instance is blocking it, it doesn't show in your profile from inside my server , only going directly to the mathstodon page.
Now that we're all gathering here where the idea is to be nice to each other, let me toot about a 1-page "paper" (not mine!) of Haldun Ozaktas that I just love. Its premises capture the ideal social media mentality so well, and then a moderately silly analysis follows (which is how I like my maths, sometimes). http://www.ee.bilkent.edu.tr/~haldun/young/foolrev.pdf
Also credit where credit is due: I don't think the author is on Mastodon but he exists: http://www.ee.bilkent.edu.tr/~haldun/
