One suggestion is to hide stylesheets from IE6, which would result in a “bare bones” non styled, though mostly functional version of a website being served to IE6 users.
Remember how we used to do something similar to Netscape 4 back in the day?
Some great discussions accompanies Dan’s post.

A summary of findings from the Web Directions’ State of the Web survey has been published, and among other things reveals that while Internet Explorer still holds the lion’s share of the browser market, web developers are increasingly making their work standards-compliant first, IE compliant second.
Despite the fact that versions of Internet Explorer still account [...]

Does the secret of Microsoft’s domination of the web browser market lie in its use of Internet Explorer’s user agent string?
And so Microsoft made their own web browser, which they called Internet Explorer, hoping for it to be a “Netscape Killer”. And Internet Explorer supported frames, and yet was not Mozilla, and so was not [...]

I have a confession to make. I have not yet downloaded and installed Google’s Chrome browser. Shame on me.
I’ve been tuning into the excited babble coming out of various discussions forums and Twitter in recent days, but I still can’t motivate myself to “make the switch”.
I realise that this stance places my reputation as an [...]

The next release of Internet Explorer may include a private browsing feature that automatically deletes all traces of a user’s web browsing activity.
Presently Safari is the only well known browser offering such an option, which is sometimes to referred to as “porn mode”, for reasonably obvious reasons…
One obvious use case for privacy browsing modes [...]

I’m starting to wonder if the new Facebook, which looks all very dandy by the way, has been especially optimised for use with Internet Explorer.
“Optimisation” harks back to the days of Web 1.0, when websites used to bear, on their splashscreens (remember those?) notices announcing that the site was better suited, or optimised, to a [...]

If SitePoint’s web stats are anything to go by, web professionals will have completely ceased using Internet Explorer in about five years time.
The emphasis is on web professionals though (who, in this instance, make up the majority of SitePoint’s readers), or those aware of the browser alternatives to IE.
Many other internet users will continue [...]

Aside from the minor matter that Internet Explorer is installed, by default, on 90 per cent (or some such figure) of PCs worldwide, much of the reporting I saw on Download Day, and the release of Firefox 3, saw IE relegated to the sidelines.
It’s faster than Microsoft Internet Explorer, but it’s not the fastest browser [...]

Though still in pre-release IETester sounds like a promising application that tests websites in a number of versions of Internet Explorer from IE 5.5 through to beta 1 of IE8.
I’ve been playing around with it, and my god, disassociated looks terrible in IE 5.5 and 6, but I already knew that.
While there’s still work to [...]

A study of the four best known current browsers finds Safari and Firefox (especially pending release version three) to be the best when tested against a variety of benchmarks.
Web 2.0 applications and sites place the focus firmly on browser performance. Anyone who still believes that the speed of your DSL connection is the only potential [...]
