Interesting that there roughly 700K daily posters but only 390K followers. I have no idea what other social media numbers are but having ~2x the posters as followers doesn't seem like a sign of health to me.

You are misinterpreting the statistics.

Having more people talk than follow is good thing and probably consistent across social media.

That's just saying the average person posts for 2 days and follows for 1. Which seems very typical if not heavy on the following.

Pointing at more people speaking than sheeping and calling that an ominous statistic seems off, don't you think?
