At the weekend the Housing Bubble site suddenly disappeared, as did its predecessor site which contained earlier archives. There's been much speculation as to why the two sites have gone. A lot of money rests on the continuation of the housing bubble and a large proportion of new jobs in the US are dependant on that continuation.
Ben Jones has now set up a replacement site that uses WordPress in place of Blogger. I wonder if we'll ever find out just why the previous blogs disappeared.
