endpoint for a sample "live" database to query?

Can anyone suggest a SPARQL interface to a database that updates often? 
I realize that all the (working) endpoints at 
http://esw.w3.org/topic/SparqlEndpoints are being constantly updated, 
but those updates are mostly augmentation of a corpus somewhere. I'm 
hoping to find something a little more newsy, like a the Twitter public 
timeline, but with information that makes more sense represented as 
triples with a SPARQL interface.

thanks,

Bob
