I had read that continuations allow you to maintain state so you can
do things like write web based tasks as flows where you can easily use
the back button to go back to a previous state.  This is what nearly
every article on continuation based web servers that I have read have
reflected, but then again, I've never done it myself, so I couldn't
make an authoritative statement on this one.

Your take on AJAX programming is interesting. Would you say that AJAX
makes web development easier, then?
