What is your policy on IE6 development?
imp: I think I'm in the minority, but I will fully support IE6 until it's less than about 5% of traffic to a website I'm working on.  Once you know IE6's quirks, it's not that hard to work around them.  I think the benefit of an additional 10% or 15% or web traffic outweighs a few extra hours of development.  Again, it sounds like most people disagree, but I developed a somewhat complex ajax app back when there was only Firefox 2 and IE6 and it wasn't that bad.  I'm not in charge of a big design studio, but that's my policy for side projects and part-time clients that I work for.  They shouldn't have to care about IE6. It should just work for them.
