Nah mate ;)

Hm. Could do that. Are there any flaws with doing that? I'd much rather
that stuff was a proper HTML content-type, because then it's more
comfortable for me to make the assumption that it *is* HTML and I can
therefore blithely parse a title out of it :)

(Memo to self: check what happens if someone tries a titleless page)

Yeah. Hm. I hadn't thought of that. Then again, are there servers that
serve pages with Content-Encoding: gzip whether you ask for it or not?
I thought you had to request it in your request, since you can't expect
that J. Random Browser will support it...?
