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 co
Get your hands on some user statistics for each individual website you're going to work on. Get the browser usage statistics from the past year, not more, no less. If there is still a significant amount of IE6 users (I personally go for more than 5%) it is probably worth supporting IE6.
If it's less than whatever you deem a reasonable percentage of users, so in my example: less than 5%, you could simply use this fact to try and convince your boss.. and ultimately.. your client.
Further arguments you can use are: Better use of CSS selectors, better support for PNG images without hacks and making the world a better place.
Unfortunately though, IE6 is here to stay.. not because the users are nefarious bastards, but simply because some companies take way too much time to upgrade their software.
