[Developers] freebase and dbpedia

[Brendan O'Connor]

Does anyone have a good sense what are the differences in data
coverage between DBpedia and Freebase?  I was comparing

http://dbpedia.org/page/Bill_Clinton  versus
http://www.freebase.com/tools/explore2/en/bill_clinton

and it looked like Freebase had more information.  But in general I
find it hard to evaluate which is "better".  It might be nice to know
what the systematic differences are.
