I don’t think this is the original powayseller of California Housing Forecast. She went by the pseudonym “powayseller”. This person is using the pseudonym “poway_seller”.
Regardless of who posted this information, I don’t see what is so inflammatory about the original post or what all the fuss is about. It could mean that the person is tired of waiting to see prices come down on the coast. It could be making the point that price per square foot is not always a good metric. It could also be a RE bull. Any of these points could have been made by the OP, but they weren’t.
Looks like simply the facts to me.
