Good questions! Sometimes I wonder too. A lot of content is repetitive, and I think that we read them over and over again to seek confirmation. (yes, we’re all subject to confirmation bias). It comforts us. I think that people here generally do welcome opposite view if that view comes with good data support. But the majority of people here believe in a housing bubble, and it shows. By constantly coming here, we’re seeking confirmation and comradeship – because beliving in a housing bubble is still a minority view in the broader context.
From time to time, you really get stuff that you won’t get otherwise — what realtors / mortgage bankers are seeing in real time, examples that people put forward (housing prices, employment, etc). So I enjoy reading these. Occassionally, you get a link to a good piece of research work – if you enjoy reading research.
I try to skim the content, and read only the part that’s interesting.
