He is a good self publicist and has milked very successfully how after about 8 years his prediction of a house price slump eventually materialised.
Yea thats his career in a nutshell, but he was a lone voice back in those days and very anti establishment. I think he borrowed his style of writing from other guys in US and UK, it wasn't unique but was unique to Ireland before people started reading international financial stuff like they do now. Suddenly when the housing crash happened he was box office and then his career as a "celebrity economist" took off.
He was shameless with regard to Brian Lenihan coming to his house for advice on how to handle the banking crisis, he couldn't keep his trap shut.
