Decay sets in the minute monetary value is involved, sadly it is part of human nature.
I totally agree 2 posts per day would take a lot of pressure off of everyone.
Those reading and participating, connecting to others (or trying to) loose out on time, creating posts, but make some great new connections....
Social Media all in all has been on the same circle and cycle for some time, you have those who will connect and communicate, others are on a hit and run, building without actually being social at all.
Thanks for insight into this discussion @charles1
