I've spent 20 years preaching "evergreen content" and here we are on a site where everything loses value after a week.
In a lot of ways, that is much like a library throwing out all books over a week old. On Steemit, a value of zero has been given to the "old" stuff, and no one will waste time on it because the money is elsewhere
Maybe that will change. If not, future forensics will name that as one of Steemit's coffin nails.
