Certainly has.
Although when Househunt first appeared on the scene he was predicting drops to 1990's levels. He was adamant that prices would resettle at averages that preceded the run-up in real-estate values and his overly ambitious predictions coupled with a penchant for blogging gave a great deal of people (albeit many financially limited people*) a lot of false hope. On VV he ran up against a lot of opposition from people who had been through Victoria's ups and downs and knew what the local price plateaus were all about.
Perhaps, but I disagree with the implication that locals who have lived through previous cycles have any particular knowledge about how the market might behave in the future. The locals in Seattle also knew that real estate only plateaus there. Until it didn't.
*By "financially limited people" I mean those who would never qualify for a home in this market even with a combined income and seemed to despise those who did. The commentary on HHV's and various other blogs were drenched with undertones of jealousy and negativity directed towards those who were in a position to buy a house, so the blog became as much a bearish take on the market as an opportunity for people to vent among friends. At least that was my interpretation.
Sure, of course there are some people that are just wishing for a $200k house because that's all they can afford. I don't really see the harm in that. You're saying you never wished for something beyond your current financial means? Of course you can't listen to that kind of wishful thinking and confuse it with analysis.
There has been lots of extremely valuable analysis done on the market these past few years. I have a much better understanding of it than I did at the beginning due to HHV, this thread, and lots of personal research (something of a hobby). It has saved us from what would have in retrospect been financially bad decisions (buying a condo to get in the market, and later buying an entry-level house that we knew we would outgrow in 5 years).
