There might be a long tail phenomenon at play here. Do you have stats on number of developers using the tech or on page views for each framework?
So it’s either a strange distribution curve, with a bump in the neck and a colossal tail, or we’re trapped in a bubble and blinded by our own crazy reality distortion field.
As to number of developers, if a lot more of us are needed to write a tiny fraction of the pages, maybe that’s the symptom right there.
