All you need is a clear and broad enough specification to accommodate modules, and you might end up building some connection bridges for popular modules not matching the specification. Everything on top of it, such as a new Microsoft browser supporting a new set of standards, is primarily an attempt to create and monopolize on a new trend.

If it's up to Microsoft, they will try to hold Web 2.0 in their iron fist with the latest twist. I have a gut feeling other, more open and less proprietary see more platforms will be chewing on their market share before they are anywhere near release.
