Hi Benjamin,

These are fair questions, thanks for raising them. Some assumptions might be
so obvious for some of us, we should state them somewhere so newcomers are
not confused.

That would actually by the typical scenario for the regular Joe user
browsing the web from different browsers, on different machines. That's
multiple certs at a given time, but also multiple certs over time when some
certs expire (it's nice to garbage collect them on the WebID profile too, to
keep it clean, but that's up to your WebID profile manager).

hum, not an assumption I've made, and my WebIDs don't have any of my friends
on it. We should not prevent anyone from using the WebID just because they
have no (public) friends, dorks can have WebIDs too. With no public friend
claims, you might have a harder time once you log in to make yourself known
and trusted, but I can imagine some cases where you could be granted some
access just based your WebID URI, and that's it.

some of it yes, at least the assertions needed for the authentication
process. Anything beyond is nice to have, best practice, part of the "WebID
etiquette".
