I personally want to encourage screen scraping. At the very least, it makes automated testing of web pages possible. Getting management to agree is a different matter . . .

I find that if I develop against Mozilla and then fix occasional breakages with IE, I'll wind up with something that works reasonably well . . .

I find this true, too. Mostly, my statement was concerned with even more niche browsers than Mozilla (Opera, Konq/Safari). I'm also blessed with a userbase that is around 70% Mozilla (or derivitive) (specifically, our userbase is mostly computer-illerate academics who were told to use Mozilla :). In such an environment, it's easy to tell non-standards-compliant browsers to go fix their bugs and leave me alone.
