When it comes to etiquette I don’t really think there’s anything in the way of social rules.

I comment on posts if I can acknowledge what’s said w intention or contribute something of use; otherwise I’ll leave a like so they’re not voided, or just stare at it and think, if I don’t know what to do with that information.

So far someone will always read what you post based off the structure and small user base, but engagement styles vary by who’s reading it
