I haven’t specifically seen anyone go off the rails when it comes to emoji usage on Lemmy; I can only comment on my particular feelings about emoji: Like any tool, emoji can be used in ways which are confusing. However, the value of these little images conveying additional context to written text is useful. There is so much of the personal voice which is lost with written words, unadorned with body language, tone of voice, and facial expressions. Emoji are like a written solution to this issue (for those that don’t pick up on context on words alone). I am fine with the usage of emoji.
