Why does MSN look like this?
Microsoft Internet Explorer website

Why does MSN look like this? Your browser cannot find our style and presentation information and as a result may not display the page properly. You are welcome to use the page as is, or upgrade your browser to its latest version which may address the problem. If you are using Microsoft Internet Explorer, go to the Microsoft Internet Explorer website to install the latest version. If you are using another browser, see the provider’s website for more information. If you are using Internet Explorer for Mac, we recommend that you use another browser to have an optimal experience on MSN.

Es decir MSN (Microsoft) te recomienda que si usas su producto para visitar su página, mejor cambies a otro.

Curioso cuando menos.
