Makes sense.
I'm not sure why I would use "your service" to do this (blog on my Google, only to have the document show up somewhere else). I see value in a service if such connector is available within Google for me to keep it within Google. Nothing wrong with your service, and it is a fantastic idea, but just saying. I think this idea is more feasible if it is available as an independent entity. I find it strange that neither Microsoft, nor Google cared to think about it, given that a word processor is a natural fit.
