Hello Jonathan,

I don't think you're taking too many liberties below, but stuff like 
this has been too obvious for some of us for a long time, so that's 
probably why I had to ask you about what you found noteworthy (and yes, 
I meant the syntax).

In my view, people who use http://dx.doi.org/... are just (at least 
implicitly) evaluating the total of persistence and resolvability of 
various approaches.

My calculations would look about as follows:


    resolvability: 100pt

    (it's not exactly perfect, but it can't get better, at least as far
     as the DOI people are concerned)

    persistence:    95pt

    (I take one point for the risk at ICANN, although I think it's
     extremely low because while they have no way and no interest to
     declare anything permanent, they have no interest at all to take
     something existing and working away (as long as the relevant fees
     are paid;
     then I take one point for the risk at .org, just because there is
     some risk there, even if small;
     then I take three points for the risk at doi.org, because they could
     indeed miss out on paying their registration renewal fees (this
     is something that actually has happened in other cases))


    resolvability: 10pt

    (I'm being generous, the race is over here anyway)

    persistence:   99pt

    (IANA registers these, and IANA is (at least currently) part of
     ICANN, so if you don't trust ICANN, you may not be able to trust
     this one, either. There are some RFCs that very clearly tell IANA
     what to do and what not to do, but that doesn't guarantee anything.)

So it should be clear why http://dx.doi.org/ is used all over the place. 
And the order stays pretty much the same even if you change the weights 
or the scores a bit (e.g. you weight persistence more,...).

Regards,    Martin.
