I'm trying to make a pitch to my boss to drop support for IE 6. I find that a disproportionate amount of time is spent on trying to make the css IE 6 compatible and that could be spend on making new features or improving usability etc.
Do you plan to do so on your future projects and if so how did you convince others to support only newer browsers?
If it's a paying gig, tell them you'll charge more unless it's an assumption going into the project. That's the only way it's worked out for us so far. I'm all for backwards compatibility but the amount of money wasted on supporting IE6 for most websites/applications is just ridiculous.
