At the very least to describe what the various communities are for. There seem to be many “general-purpose” communities and I do not understand the difference between them, and there are also communities that seem to be duplicates of one another, namely /c/hexbear, /c/den, and /c/feedback.
Additionally, I believe having a wiki blurb for common “emoji” would be beneficial. Who is the person in the image? What is their politics? Why is their image immortalized on our platform? What are some of the common usages of the emoji in terms of communicating a message or emotion through shorthand? Often I am faced with comments that I find incomprehensible due to the use of an emoji that I do not understand.
The emojis are like a fun hidden mythology to me, I don’t know what many are or where they came from but I just use them for emphasis like regular emojis
Over time I learned how they were used like an extra part of the online dialect. If you don’t know what someone means with their emoji hieroglyphics it doesn’t hurt to ask usually. Sometimes people can be rude to others that ask legitimate questions though which is a tendency that should be destroyed.
