Trulia

In looking to buy a house in or near Marathon, Florida, I have used Trulia, Zillow, and Realtor. Each has weaknesses and good points, but by far the weakest and most frustrating was Trulia.
My major complaint has been the alert algorithm. As a potential buyer, I wanted to know when a property that met my criteria was newly listed, and there's the rub with Trulia. If the alert said "Trulia Suggests: 1 New Home near Marathon", more often than not it was not what I call near. To me, near means the target city in or within fifteen or twenty minutes away. Trulia does not define "near" the same way. I am constantly getting alerts on homes forty minutes to an hour away, mainly in Key West, Key Largo, Tavernier, and Islamorada. The topper is getting alerts on homes in Lighthouse Point, Florida, 159 miles away. Not just once, but often. That is not near.
My search criteria were for single-family homes with asking prices between $800,000 and $2,500,000, yet I constantly got alerts on raw land, condos, duplexes, and businesses, as well as homes at $300,000 and at $11,000,000.
Trulia reports when homes are sold, and the prices they show are ludicrously wrong. A friendly realtor gave me a guest pass to MLS which lists the actual selling price. One home Trulia reported selling for $800,000 actually sold for $2,400,000.
The Trulia iPad app gives new meaning to the term glacial, and when it finally boots up.
A significant percentage of Trulia listings are just plain in error. They showed a picture of a Marathon home that was actually in Tavernier, another of a home that had not yet been built. The term "new listing" means nothing to Trulia, which routinely sends out alerts on a "new listing" that has been on the market for a year.
Zillow recently bought Trulia, but they haven't changed anything noticeable. They should fix their own search algorithm and then fix Trulia's.
Several months ago, I sent a letter to Trulia explaining the ineffectiveness and errors of their search algorithm (I was a software developer for many years and understood the flaws of the algorithm). I suggested ways to fix it, but Trulia never replied nor obviously tweaked the algorithm to improve it.
It is too bad, for Trulia could help the prospective buyer informed. I hope they fix it.
