along with the exhortations to new folks to use content warnings, I would like to exhort masto veterans to be patient with new users, and to *please* include explanations of common abbreviations so the new folks can get a handle on them. examples:
pol = politics
uspol = US politics
mh = mental health
tf = transformation
+/- signs = positive or negative modifiers, so "uspol +" would refer to a story about US politics that is actually good (for a change).
feel free to reply to this with other common-ish examples if you can think of them!
