(I realize that some of these suggestions would best be used simulatenously, e.g., #newPaper and #preprint have obviously different content. What I am searching for is a common tag for *threads* explaining research articles, not only posts announcing a new publication 🙂.
I had to drop one tag bc of the 5-option limit in polls, and I went for #mastoPrint as it was my own suggestion.)

Some further thoughts:
One could combine these tags in a standardized way with research field names, e.g. #newNeuroPaper, #neuroPreprint, or #neuroPaperThread.
Also, please remember to use #camelCase or #CamelCase notation in these tags for screenreader accessibility!
