Gabriel:
I have run through the data and have a rough estimate of how many of our
pageviews are requested from browsers w/o strong javascript support. It is
a preliminary rough estimate but I think is pretty useful.
TL;DR
According to our new pageview definition (
https://meta.wikimedia.org/wiki/Research:Page_view) about 10% of pageviews
come from clients w/o much javascript support. But - BIG CAVEAT- this
includes bots requests. If you remove the easy-too-spot-big-bots the
percentage is <3%.
Details here (still some homework to do regarding IE6 and IE7)
