As author of the charter, that's my job :)  Likewise,  how does
WebFinger not solve your problem?

Again, I consider things like having multiple 'standards' for the same
problem (i.e. the microformat/RDFa/microdata issue) a standardization
failure as it results in incompatible systems. Furthermore, a successful
working group requires resisting scope creep, including the ever-present
temptation to re-inventing the wheel.

If you have another solution to the Discovery problem that is superior
to WebFinger, you are more than welcome to write it down and I'm sure
we'd all be happy to discuss. However, my preference is that the
open-ended scope of the Social IG may be better suited for experimental
work and that yet another discovery mechanism should probably not go
Rec-track. We already have 3 Rec track deliverables, two of which (API
and Federation) we should probably focus on :)

If we're going to use it, I'd think we should update it to be JUST a mapping from email to profile URL.  That is, http://w3.org/.well-known/wf2?email= sandro@w3.org would http redirect to http://www.w3.org/People/Sandro.   And that would be the entirely of the standard, give or take edge cases.
