BTW: On occasion I design websites and am also wont to do that in InDesign (because I am more comfortable with it & because the type tools of PS suck — the new PS CS6 beta is a great improvement) — after everything has been okay’d by the client I supplement the ID-doc with annotations re measures, sizes, etc. and send that off to a web-designer. Works great.
