Thanks everybody !

Could not imagine that this simple question would trigger such an activity.
Actually my naive "quest" was to figure how many people had actively
published, and possibly still maintain a FOAF profile for themselves, vs the
number of profiles stored and maintained in a proprietary social system, vs
a profile computed out of their activity on the web for any purpose.
Browsing all the answers makes me wonder. I was not aware of so many sources
of FOAF information (to tell the truth a great majority of domains quoted by
Michael in his 25 top list were totally unknown to me until today). The
number I had in mind when asking was rather abou FOAF profiles actively
maintained by some "primary topic" aware of what FOAF is and deliberately
using it to be present in the social semantic web. I suppose this number
really represents a microscopic part of the millions announced, but I do not
know more about it at the end of this day. Except that most FOAF information
is certainly produced without people subject of the triples even being aware
of it, or even knowing that FOAF exists at all (supposing they are living,
real people).
Actually it's quite easy to produce FOAF out of any social application data
with an open API. So the millions I read about are simply an image of the
millions of users of social software using open API, plus the growing number
of people for which "public" data is available such as people listed in
Wikipedia and Freebase.

So tonight I would turn my question otherwise : Among those millions of FOAF
profiles, how do I discover those of which primary source is their primary
topic, expressing herself natively in FOAF, vs the ocean of second-hand
remashed / remixed information, captured with or without clear approbation
of their subjects, and eventually released in FOAF syntax in the Cloud ...
