Citations to social media posts?

I've seen this happen a few times in academic talks as well as peer-reviewed publications: someone quotes and cites a post from a social media (like a post here).

Under what conditions do you think this is appropriate? I'm not so sure it's a great idea.

The thoughts I post here are somewhere between "musing things through" and things I'd write in an archival publication. I don't want to have to hold them to the same bar that I hold for archivable/publishable words (if I did, I'd stop musing). I'm dismayed to think that my musings might be used in a publication to make some point.

But I can also see when it might be relevant/important.

My take is that we should hold words on social media to the same bar as traditional "personal communication" where we seek permission from the author to use the quotes (definitely in publications; ideally in formal talks as well).

Any disagreements?
