Please see the “condensed time line” section (the next one) for a time line of how the Xerox saga unfolded. It for example depicts that I did not push the thing to the public right away, but gave Xerox a lot of time before I did so. Personally, I think this is important. I will post updates and links to the relevant blog posts in there in order not to make total crap out of this article's outline.
