It is not voyeuristic, it is personal.
It is meaningful.
Is it time or motivation?
It's mostly the scarcity of the former. A lot of things to build in the physical environment, so less time to build virtual content. Making long posts have turned into a guilty pleasure I feel I can't afford but that's because there are some other time-consuming habits like looking for news and analysis online. One needs to find a balance, I know. Working on it.
