ADMINISTRIVIA: Time for my periodic ask. For some reason, links to wist.info are not generating #PreviewCards here on #Mastodon (though they do in Twitter, FB, diaspora*, etc., and they test clean on various #OpenGraph testing sites). E.g., https://wist.info/euripides/60428/ .

Since such title cards would include title info, that would be helpful for readers here.

Anyone know anyone who might have a clue as to what's not quite right?

Appreciate any boost you can give.
