Something that I find really fascinating about the culture of various groups is how they use emoji vs the textual meaning assigned to the emoji.
With regularity I see the 😂 emoji being used as a way to react to something with laughter. That’s the :joy: emoji. Which I get, the common representation of it is a face with mouth open in a wide grin, and tears coming from the eyes. But the sentiment I see being expressed with its use to me almost always seems more aligned with the 🤣 emoji, the :rolling_on_the_floor_laughing: emoji.
From the textual designation of these emoji it would seem to me that they convey significantly different meanings, but common use among sighted folks conflates them heavily. I don’t know if this is a problem per se (I don’t think it is), but as I am sighted myself I’m not entirely sure.
