Unfortunately within the finance industry we are surrounded by brain dead plonks (generally economists) who make endless predictions all of which turn out to be wrong. Disappointingly these idiots are never held to account for their all pervasive cretinism.
Pundit Tracker is a US centric site but at first glance it seems like a good idea. Each idiots predictions are noted, catalogued and then repeated back to them when they make another prediction.
Their blog which looks at Pundit Excuses is also worth a look
