How can we tell if there are way too many posts?It's easy to calculate. Yours is post # 1487660. Check back in exactly 24 hours, subtract this number from the number of the then current post, and you will have your number. Monitor weekly, and report back in a year.
There are too many variables to monitor just for one year. It needs to be done over several years. I am not sure if natural disasters and nuclear attacks would increase or decrease postings.
