I post here for the chaos, criticism and the cryptocurrency knowledge discovery this forum discuss on.
The Bitcointalk, like the organic human society which comprises of all sorts of people making up the society can not be any differently from having the different types of posters in the forum. It is left for each forum user to filter the forum for their self based on what they are here for.
But op, you did not throw much light into what really led to the setback of your project, was it promotional challenge or it was a problem of the project standard. Is it not with this same audience the Bitcoin project rose with and became a standard to date, what went wrong with the audience regarding your own project?
But we all do lots of things that are wastes of time, don't we? Is posting here more productive than playing an FPS? From doomscrolling on Facebook? Then watching the EPL? I think so. As far as "leisure activities" go, at least this one allows you to learn something... occasionally.
I will not count it for myself a waste of time wasting the EPL matches and football generally is a sport that brightens my countenance. Something that has that effect on me can not be a time waster.
