M$ are at it again......
Can't say I'm surprised. Annoyed yes, but never surprised with anything they do. It's just another way to try to get people to use IE.
Here's a thought, if it happens again, everybody that's a msn user should report the website as not working. Let's see how much they like getting bombarded with emails/phone calls from dissatisfied customers. :-)
Another way to look at it is this: people have got rid of IE and are using other browsers, what would you do if msn stopped showing up on your browser? I'd certainly not bother with msn's website (mind you, I only use it for messenger and hotmail, for which I don't need msnmessenger (I use Trillian) or the web site (ok, I use outlook, but it's easy to use and I can't be bothered to try different mailers). This way, msn's website is only hurting itself (ok, maybe just a little).
