Regarding phasing out support for IE 6 across all 37signals products.

When I made the latest set of cosmetic changes to the blog, I decided I would no longer test in IE 6. If you are using Windows then you really should be using Firefox (or if you're one of those people who don't like v3, perhaps Opera). If using Internet Explorer is "using the Internet" to you, then you should accept the default choices you are offered when accessing Windows Update (which will include IE 7).

When I first started working as a Web Developer I was still testing in Netscape Navigator 4 and Internet Explorer 4. IE 5 was painful to support and IE 6 followed in the footsteps of its parent. IE 7 isn't perfect, but at least there are less bugs for developers to deal with.

Now if only the rest of the world would follow suit, then I could stop supporting it when developing sites for others.
