In terms of a debate though, they are a little tedious. There are blogs out there which track the individual price changes so while I agree that asking-price drops qualify as a leading indicator of a turning market, I'd say that linking or referencing an appropriate blog would have been sufficient if you really needed to do so in order to support an argument.
It was the posts which only contained price drops and no debate/argument/opinion which brought things to a head.
I don't think that those blogs were there when they (the asking price drops) were first being published (I could be wrong about that but I was only using AAM for a complete HP debate so was not looking elsewhere at the time).
Still if I had been a buyer I would have wanted to see them which would have given a more up to date feeling as to what was going on in the market instead of relying on out of date PTSB/ESRI reports
