Ah, that makes sense. It would be interesting to note which accounts seem to be on an "extended" hiatus, though. Perhaps arbitrary time cutoffs plotted against their cumulative inactivity.
I assume that Steemit doesn't cull accounts over a certain age with no activity? Was curious about that detail.
Of course, Steemit does not care for who is active and who is not. The plot of cumulative inactivity would be interesting. If no one cares to make one earlier, I'll add it to the next post in the series.
