> sad - that there could be demand for a big red flashing IRL “busy”
Busy is the virture most people want to signal most of the time. Next time someone ask how things are tell people you are not busy, its elicits a similar response to telling people your distant uncle died.
Depends what you mean by busy. I use the "free" designation option to plan work in my shared calendar. I am busy but I am also free for a meeting if needed. In server parlence this might be an async batch processing job.
Peope who do 0.8 hours work and collect a full time salary while playing golf and pretending they do 8 are rare I suspect.
