StumbleUpon should fix this quick and easy by changing the user agent string (overridable in the registry). The last thing the world needs is inflated IE6 stats.<p>The whole "companies need their internal applications" is bullshit. Firefox and Chrome do not break an installed IE6 on a computer. People can continue to use IE6 for internal sites, and a real browser for other sites.<p>Any IT department that forbids installation of Firefox needs to be brought outside and proverbially shot.
