Trulia is a real estate search engine.

Or, as they put it:

Trulia is a real estate search engine that helps you find homes for sale and make smarter real estate decisions in the process.

Use our interactive Heat Maps to view real estate activity across Boston ZIP codes and in other nearby cities. See local real estate trends, and compare your home to recently sold homes and similar homes for sale in Boston, Massachusetts.

It's like a Multiple Listing Service, but with maps. And, some additional search and analysis options.

[It's like a Multiple Listing Service, but it doesn't pull its listings from MLS. Agencies add their listings manually. Therefore, it's not as comprehensive as MLS, at least not in Boston. For example, MLS has 248 listings in the 02116 ZIP code. Trulia has 96 listings. They have to get better at this ...)

Overnight, Trulia released "Trulia Voices". I was able to test it out in beta. It's a cool idea.

Trulia Voices a community for you to find and share local real estate information that matters most to you! Want to know if it's a good time to buy or where the great dog parks are? Just ask.

All questions and answers are submitted by people like you in the Trulia community—local residents, home buyers and sellers, and real estate professionals.

Basically, it's a question and answer forum. Questions are posed by visitors to the site - perhaps someone from out of town who will be moving to Boston and wants to know which neighborhood to move to. Answers are provided by other visitors to the site - say, someone who already lives there, or, maybe a real estate agent who wants to capture the buyer's business.

It seems like a great idea and a natural fit for what Trulia is doing.

Some agents may think a company such as Trulia is a threat to their business model. There's nothing stopping a seller from listing his or her home for sale on Trulia, bypassing a sales agent (and, perhaps, a buyer's agent as well).

I guess. I'm not too concerned. As I've stated before (ad nauseum) I don't fear these new real estate services. Their target markets are different from mine.
