Prolog missed the Web 2.0 Bandwagon

Web 2.0 is all about incremental content!

It wouldn’t do the ghost text, only assist
it. There was a misunderstanding how “ghost
texts” work. Maybe you were thinking, that
the “ghost text” is part of the first response.
But usually the “ghost text” is a second response:

Well you don’t use it for your primary
typing completion which is preferably fast.
The first response might give context information,
for the second request which provides a
different type of completion.
But the first response is not responsible
for any timing towards the second request.
That anyway happens in the client. And it
doesn’t hurt if the first response is
from a stupid channel.
