@Alhadis -
Yes, it’s not a pleasant era to live in where non-computer-savvy people are forced to click past warning dialogues, but if people don’t put their foot down sooner or later, it’s never going to end.

This is where I really disagree. I'm 100% ok with dropping support for anything that you don't want to support. If WordPress doesn't want to support IE7, then thats cool.

But to nag and moan and more importantly, stop people using the software, because we don't happen to like the browser or OS you're using... it's close to childish.

It also completely ruins the User Experience for "non-computer-savvy people", which is funny given that the WordPress core now has a UX person on the core team (it's ok, she only tests on Mac's anyway, it's how the WP3.3 beta was released with a menu that didn't work on IE, oh obviously there's no testers in the core team either).

I'm not saying you have to support anything you don't want to, but obey Wheaton's law: https://twitter.com/#!/wilw/status/5966220832, and honestly, that HUGE browser nag thing really breaks it. Especially with all the false positives, and the fact that the browser detect, y'know, can't accurately detect browsers... /facepalm

Seeing a warning message – as well as an unsightly mess of a website, should be enough to get the point across to the user.

It does, it says "don't use this website".

It doesn't say " wow dear, this website is right, I had better upgrade my browser, i should listen to websites and banenr ads more often, whats this? vi*gra? I'll click that, oh what now? you want my password - ofc - i mean, all people belive banner ads, especially because its in Red. Wow, I've won first prize, I'll click everything I see......."

We've spent 10 years teaching people to ignore big bright things that tell them to upgrade. especially if they look like banner ads. it is, frankly, muppetry to believe that they'll magically trust this annoying banner ad because it's near the WordPress logo!
