I wrote a piece about IE6 for .net, interviewing Remy Sharp. Sharp argues people should stop banging on about ditching IE6:

We all know IE6 should die. Microsoft knows IE6 should die. Heck, even IE6 knows it needs to die. It’s been walking around like a fucking zombie for years.

He says either don’t support the browser (and potentially lose clients) or just offer support as a separate charge. I agree with this (as might be apparent from the article itself), and it seems most of those commenting do too. My favourite is ‘leegriffin’ with:

You don’t see mechanics saying they simply won’t service that old 1990 Ford Fiesta because it can be a pain in the backside, they just charge appropriately.

Exactly.
