Having worked with you for a while, I highly rate your analytic ability,
and the way you can take a problem, get to the heart of the matter, and
reframe it.  You also have good in depth knowledge in a number of areas.
But being a regular coder and user of these systems, on an hourly basis I
think gives further insights that are not easy to communicate over email.
At this point my comments are high level.

Let's see if this works.  My first use case was social.  As part of the
indieweb community I wanted to add friends to my roster.  To may complete
amazement there wasnt a way to do this.  But a hope to expand the concept
of "blogrolls".  At this point I realized indieweb was a microblogging
system, not a social system.  I tried to develop things in this line but
Tantek pushed back saying it was 'not a priority'.  How can a social system
not have friending.  So I found this was much easier to do in RDF and
Solid.  That's just one example of many.  I hope it does not because the
focus of this thread, though.

OK, so you think adoption doesnt need to be factored in and I do.  I think
that's a reasonable thing to disagree on.  You keep calling straw man but
when I ask you why, you dont respond.  It's not a good way to communicate,
frankly.

Again we disagree.  I said there should be an *explicit* mapping from
webmention to a linked data format, so that implementors know what to do.

In fact you are implying that if you prefix source and target in form
encoded variables with a namespace it becomes isomorphic with a linked data
serialization.  It doesn't does it?  This is under specified.
