http://sphinn.com/story/55504 - When you click through be prepared for a VERY long wait, and it might crash your browser (Hope it doesn't) but basically the blog post being Sphunn is accusing Trulia of cloaking for the Google user agent.
I have for the most part tried to stay on the sidelines with the whole Trulia deal, but this sort of gossip I always find interesting for some reason (I guess because I want to see how it plays out with Google) - if in fact they are cloaking, I can't see how Google could ignore it.
