Internet Explorer 8 will probably break websites but has compatibility view to "fix" the problem.

The hits just keep on coming. Many websites will break when Microsoft releases Internet Explorer 8 out to the world very soon.

By the end of 2009 it will be on Millions of computers.

One of the features Microsoft has added is called “Compatibility View” which will help show those pages which do not conform to the new standards. You will be able to download a list of not compatible sites from Microsoft into your browser (a pain) so that they show in compatility view.

Something else IT will eventually inevitably have to manage. Sigh… for more info see here:
