I had uploaded a doc looking at OAuth & ID-WSF to Google Docs.
I wanted to publish the doc in this blog.
So, the very authentication model that OAuth & ID-WSF are designed to deprecate (i.e. a Consumer asking for User credentials at a Service Provider) is used to push a document that compares the two from Docs to Blogger (before you say anything about both being Google properties, it would work the same way for other blogging platforms).
Didn't work anyways.
