[Data-modeling] new Freebase application online: Thinkbase

[Robert Cook]

I also think this is a great pice of work.  Regarding performance, it  
might make sense, assuming that the server-side code isn't too  
complex, to port it to ACRE, our new javascript execution  
environment.  This would localize multiple sequential MQL queries near  
our primary servers, dramatically reducing cumulative latency.

Also, if you send us the queries you're trying to do, we might be able  
to help make them more performant even without changing your  
architecture.
