When thinking about HPC one needs to bear in mind that there is a difference between the message of the forum and the type of people who now post there.
The points made by posters on the forum about an asset bubble and the reasons for it were accurate. But as this has played out over such a long time, all the decent posters have moved on from the forum for various reasons. After learning about the subject there's only so much that you can chat about it before the subject becomes exhausted. This has led to a filtering effect where only the misogynistic and racist tin foil hat nutters remain. These are not the same posters who were there at the start of the forum and who were making intelligent comments.
The 'nutcase' posters feel superior about having some kind of special insight, yet most of them weren't the ones who actually figured it out. They don't understand that just believing the opposite of what everyone else believes won't provide the right answer. You also need to recognise when the majority of people are mistaken. There is more to being a contrarian than calling everyone else that doesn't agree with you 'sheeple'.
In the end, the forum has become a sad shadow of what it once was. A place for the angry and dispossessed to rant at the world and the system that keeps them down.
So what's the future for HPC? The crash is in the final stage where things are turning scary for everyone. It's becoming plain for all to see. Then there will be the long drawn out stagnation of the housing market and the economy where no one even considers buying unless they want to live in the house. The subject of the house price crash will become irrelevant and the remit for the forum will be over. If they couldn't keep their decent posters while the crash was actually taking place because things move so slowly, they certainly won't keep them during this phase.
All that is left to the forum is to try and reposition itself as some contrarian economics forum. Unfortunately they no longer have the quality posters to achieve this.
