[Javascript] Strictly speaking (Was Javascript Detection)

Paul starts a mini-thread about XHTML strict to which David replies:

While I have occasionally used document.write(), I've always thought it to be
a "dirty" way to alter pages. It sure is easier than using DOM methods but
does it not lend itself to creating errors of well-formedness and making
subsequent changes to the page more difficult - especially in a growing AJAX
world? Does document.write() have a place in a progressive enhancement
environment?

I'm just curious what others think.
