From 12 noon to 1:30 EST on 12 November 2015, 8 forecasts from 11,000 forecasters, or about 1 every 12 minutes.
I’m not sure how many tweets/employee/minute Twitter has, but. No wait, actually I do. Twitter has 645,750,000 tweets/day. It has 3900 employees, plus or minus 8%. So it has 115 tweets/minute/employee.
Let’s say GJ, Inc. has 10 employees. Based on lunchtime numbers, let’s say it has 192 forecasts per day. So it has 0.01 forecasts/minute/employee. For a site with no advertising revenue and no user subscription fees.
It’s Internet economics. Thank the Many-Faced God for free stuff!
