idea for Microsoft: blogging service for tablet pc users!

just imagine, something like www.blogger.com with handwriting user interface
so that users could write their blogs with tablet pc!!!

I reckon that if MS woudl launch such blogging service - exclusively for
tablet pc users (the unique ID/key of tablet pc needed) - then it woudl
popularize tablet pc platform significantly!!

good idea?

come on, Bill Gates, just show the minimum of innovativeness and launch
it!!!


PS. I wonder how to do handwriting in server side application? with ActiveX
?
