Microsoft has a problem with not specifying fallback fonts for non-Windows machines: http://wsld.me/KPlc

Looks like they're setting the font explicitly to 'Segoe UI' and nothing else in many spots. Telerik, a .NET CMS provider does a similar thing.

I suspect they believe only visitors with Windows machines will ever visit their site.
