It seems like you're comparing the current situation to more like ~20 years ago than ~10 years ago.

In 2011, both Rails and Django were well established and used heavily.

And in 2011, not too many people cared about IE6 either (some did, but even the big sites didn't support it anymore).

Even GitHub was used quite a lot in 2011, and was well known.

Still, I think you're right, it's just a different time scope...
