Web Tools and Browser Testing

Our FoxIE web devs discuss techniques for supporting modern browsers and not leaving legacy users totally behind. They also address the risks and alternatives to common feature detection methods and browser sniffing.
http://web.tweetdeck.com/ does the (bad) browser checking technique very blatantly. In IE (even 10), this site doesn't even work. If you change the user agent, you can log in, but that's it. The worst part is, that it USED TO work.
Thx for the tip on Tweetdeck.

I changed the user agent and managed to log in, but this happened:

@PSRBF6: Those classes are added by Modernizr following a series of feature tests. I just logged into tweetdeck using IE10 and found that while much of the interface works, the in-flow of tweets was broken, as well as a few minor layout issues. Hope they get it fixed - it's a great service.
Jonathan, thanks for sharing that bit knowledge. :-)
My experience on the site yesterday was the same as Jonathans.
