There definitely is a critical mass needed for social media. Reddit hit critical mass around 2012 when digg imploded. When I joined reddit in like 2010, it felt very much like Lemmy currently does.
I think that’s a major problem with Lemmy, because it’s so disjointed it’s hard to hit the critical mass needed to keep conversations interesting and fresh.
Averages are fine if you have a pretty clean dataset. But if you have significant outlier data, like most do, averages can be misleading.
Mode and median are generally better ways to get look at a “central tendency”
This is why “average” is a shitty way to measure what values are likely.
If you have a thousand people who have a thousand dollars, and one person who has a billion dollars, the “average” person has a million dollars.
