More msie6 dissing with IE6 update

As posts about how bad we want msie6 to disappear are the latest craze;
This morning I implemented “IE6 update” on this blog. This little piece of javascript displays an official looking information bar that encourages them to upgrade and links to the official MS IE8 website.
Maybe this is on the edge of what is ethical, because we’re actually faking an official browser-message, trying to trick users in clicking that link. And maybe they can’t install IE7 or 8 (or another browser) because they don’t have administrator-rights.
But if users aren’t aware of the problem their ancient browser creates, they won’t bug their IT-staff now will they?
