Weird and funny is the idea of the unicoins. Who created it? Does this influence totally TeX.SX? What is the purpose of it? Was this a feature request?
Unicoins is a short-lived April fool's initiative from the Stack Exchange group. Apart from the outrageous and sometimes hilarious discussions about Unicoins on Meta.SO, they won't make you richer, not here nor in the real world.
