"two stanards for the same purpose"

"it is not in the interests of users like you and me to have two standards for the same purpose”.

While I'm not defending MS, why did the open sauce community decide to invent a new format as well to sit alongside all the other formats that already existed for "documents"?

E.g. what was wrong with extending good old RTF that has been around for yonks?

Oh yeah, sorry, must be because RTF is not XML and enterprisey enough for the cool kids to play with.
