Stenberg: The state and rate of HTTP/2 adoption
At his blog, Mozilla's Daniel Stenberg has written up a detailed
look at HTTP/2 adoption—on both the browser and server
sides, plus forays into proxies, content-delivery networks, and
non-browser software as well.
"My prediction: We’ll see >10% usage by the end of the year,
possibly as much as 20-30% a little depending on how fast some of the
major and most popular platforms will switch (Facebook, Instagram,
Tumblr, Yahoo and others). In 2016 we might see HTTP/2 serve a
majority of all HTTP requests – done by browsers at least.
