A few years back Peter Kafka wrote an article [1] about how joe/joan-shmoe twitter user will probably never have their tweets read by anybody at all. It was astonishingly small number of folks who broke 500 followers (writing 3/4 years ago)
ex. “The median Twitter account has a single follower. Among the much smaller subset of accounts that have posted in the last 30 days, the median account has just 61 followers.”
It is from a few years ago, maybe things have changed but if that's the experience of the average person why invest time in it?
