I’m also of an age where emojis are more distracting than informative, but I notice younger colleagues use them liberally and with significant information value.
Like if I were to write three bullets about the results of an experiment, I would use three actual bullet points for maybe describing the hypothesis, the test methodology, and the result.
Plenty of people I work with would use a light bulb bullet for the hypothesis, a clipboard for the methodology, and a chart up or down for results.
It’s overly cute to me, but it works for them, and it does kind of provide a visual index.
