Is a little knowledge dangerous?

My husband forwarded House Miners to me today. The information from three simple drop down menus is analyzed to help you decide whether or not to sell or buy a house now.

The parameters are:
1. Where is it? - Country, Province/State, City
2. I'm thinking about -buying or selling
3. How much is....?- the house price and if applicable the monthly rent
4. Hit Analyze and you're done.

After "careful" analysis the site will advise you whether to sell or buy.

Is it really that easy? Do people honestly make large financial decisions based on a website that couldn't possibly have even the slightest idea of well... anything?

Perhaps I'll call the psychic line and ask if I should get a divorce or maybe I'll throw the dice and have that many children.

I think you get the point.
