[Developers] Built With Freebase: Creative Commons Car Pictures

[Reilly Hayes]

About 25% of the objects typed as /Common/Topic have that as their  
only type.  Virtually all of these are topics imported from  
Wikipedia.  Some of them don't belong in Freebase, like Discography,  
List of x, History of x.  Others we don't yet have schema for.  Many,  
of course, can and should be typed.

There are millions of objects not typed as /Common/Topic that do have  
another useful type.  /Music/Track accounts for a large part of this.
