Here is the current top 25 for foaf-search.net (Number of RDF documents per
second level domain). dbpedia is not included because we used the dumps and
livejournal.com was not crawled completely. Not all RDF documents are about
persons. We index every document containing a foaf:name or foaf:nick
predicate.

is a short journey :-)

Hi All,
I was looking at the number of foaf files on the web over a year ago now,
output looks like so :

Just trying to figure what is the size of personal information available as
LOD vs billions of person profiles stored by Google, Amazon, Facebook,
LinkedIn, unameit ... in proprietary formats.
At www.foaf-search.net, we have ca. 3.5 mio instances of foaf:Person.
The biggest chunk out there is probably livejournal.com with more than 25mio
users which we cannot index all right now (we have 221090 of them).
Another big one is hi5.com but the FOAF is quite broken so we don't crawl it.
gmail at one point were publishing foaf profiles ... so that's quite a few more
facebook graph is not quite foaf but certainly machine readable JSON,
and could easily be transformed to FOAF, so that's another chunk
there's a few bridges too such as ones last.fm, flikr and semantic tweet
So including bridge I'd guess 250 million, 99% should be alive today,
but that number will fall over time (obviously)
