The reason is because Microsoft tries to make 'standards'. Which aren't standard because they're MS only.
Retarded webmasters (usually under-13's) like to use these crappy MS 'standards'.
Major companies that do this are few and far between, those that do only cater for only 1 browser (be it IE, Mozilla whatever) are quite frankly *
stupid*, because the web was not made to be cut into little tribal quarters and also --> they lose business.
If people (mosty MS) would actually conform to standards then no browser should be locked out.
And yes, I do understand that standards are often slow to be approved etc and this can cause problems, but still it's the right way. (look at XML)
