> The fact that 99% of people are too lazy to learn a new trick shouldn't really hamstring people into using 30-year old tricks to get to a decent latency!

What amazes me is that in this <1% there is not even Google, which implemented push in its own protocol. Any insights on that?

Looking at their highly optimized code on google.com, my guess is that they already use all the tricks that work on _every_ browser. And it might not make much sense for them to have two builds: one elegant, with multiple files per page for newer browsers, and ugly optimized blob for older ones.
