[Data-modeling] new Freebase application online: Thinkbase

[Christian Hirsch]

Robert, Brandon,

Thanks for the feedback. Developing Thinkbase surely was lots of fun.

Regarding scale, yes, EC2 would be an option we've started looking into...
Regarding performance, I don't think ACRE would be an option right now, but
I might look into that at a later stage. But I will come back to your offer
to help improve performance of the queries.

Cheers,
Christian
