No, I'm not talking about the housing bubble that's been center page in the media for the past couple years. I'm talking about the bubble in listing aggregation services that is very quickly inflating to huge proportions. Everybody and their cousin is working on some scheme to aggregate listings at a national level in order to draw (and monetize) consumer eyeballs.
Just in the past week Zillow, HouseValues and HomeGain all launched initiatives in this space to go along with Trulia, Oodle, Move, PropSmart, Google Base, Point2, Craigslist, and I'm sure at least a dozen others in the next year. Combine that with the fact that about every real estate agent and broker on the Internet offers local IDX feeds on their website, and if that isn't a bubble, I don't know what is.
Yes, I know the rewards for a potential success are huge, but we seem to be seeing the typical, follow the herd mentality taking place, which is going result in a lot of companies being burned. The key factor in this whole equation is inventory, despite all the hype nobody outside of Move (realtor.com) has been able to capture a significant share of the listings.
I say "let them burn!" We don't need them, we need to take our information back.
The Internet is just a medium for real estate. The true sales and knowledge come from the Realtors in the trenches that know the ins and outs of the local market.
