I ain't got a problem with synchronous calls. Its just that I had the
need to rant because the rift between you guys and simple developer
folks is getting deeper every day. If somebody fucks up his web site
because he doesn't get the differences between asynchronous and
synchronous calls, that's his prerogative.

nothing going on while your single-threaded code waits for the XHR to
complete, and so it's still bad UX. Solving the bad UX would require you
to deal with the scheduler (spawn microthreads that do other things so
it's not bad UX). Regardless, ES-discuss isn't fond of co-routines, so
that's not gonna happen.
