Hi Gerard,
I was not trying to judge here. I was just saying that it wasn't much data in the
end.
For me Freebase was basically cherry-picked.
Meanwhile, the data we extract is more pertinent to the goal of having Wikidata cover the
info boxes. We still have ~ 500 million statements left. But none of it is used yet.
Hopefully we can change that.
Meanwhile, Google crawls all the references and extracts facts from there. We don't
have that available, but there is Linked Open Data.

Hoi,
I totally reject the assertion was so bad. I have always had the
opinion
that the main issue was an atrocious user interface. Add to this the
people
that have Wikipedia notions about quality. They have and had a
detrimental
effect on both the quantity and quality of Wikidata.
When you add the functionality that is being build by the datawranglers
at
DBpedia, it becomes easy/easier to compare the data from Wikipedias
with
Wikidata (and why not Freebase) add what has consensus and curate the
differences. This will enable a true datasense of quality and allows us
to
provide a much improved service.
Thanks,

Not much of Freebase did end up in Wikidata.
Dropping here some pointers to shed light on the migration of
Freebase
to Wikidata, since I was partially involved in
the process:
1. WikiProject [1];
2. the paper behind [2];
3. datasets to be migrated [3].
I can confirm that the migration has stalled: as of today, *528
thousands* Freebase statements were curated by the community, out of
*10
million* ones. By 'curated', I mean
approved or rejected.
These numbers come from two queries against the primary sources tool
database.
The stall is due to several causes: in my opinion, the most important
one was the bad quality of sources [4,5] coming from the Knowledge
Vault
