As web developers, we are all responsible for producing quality web applications that are expected to "just work" by our clients. Part of that quality is (or should be) browser testing. Yes, it's tedious and often frustrating, but the real question is, do you do it, and what browsers/platforms do you test? Post any comments you have about your testing on the message board (http://webdesign.meetup.com/17/messages/boards/thread/8827326/#34708223).
