Nice work, some comments on the copy of 1-4 below:

I'd disagree with this. Reference implementation always implies that other
implementations should copy it as much as possible, and Ubuntu is no way
that. As long as Ubuntu still uses a hybrid of Sys V and Upstart jobs, it
can never be a reference implementation.

It may be that you mean what the document corresponds to, in which case use
a different term ;-)

Events can be more than just signals, I've made a point of documenting this
recently, so this just confuses the issue.

   - Events are like
Signals<http://upstart.at/2010/12/08/events-are-like-signals/>
   - Events are like
Methods<http://upstart.at/2010/12/16/events-are-like-methods/>
   - Events are like Hooks<http://upstart.at/2011/01/06/events-are-like-hooks/>
