Google has just filed a new patent concerning doop content:
http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.html&r=1&p=1&f=G&l=50&d=PG01&S1=20070233808.PGNR.&OS=dn/20070233808&RS=DN/20070233808

I tried to read it to figure out what they are trying to do, but couldn't get any specifics out of it.

If anyone wants to try and "translate" the patent, we'd appreciate it.

The main point is that Google is trying to deal with doop content across multiple sites. It's up to us to stay a step or two ahead.
