Today Skyhook Wireless is rolling out a private beta for MyLoki, a new service for Loki. Using your current location, MyLoki can show friends where you are - check out my email signature for an example. [It said the person was in Boston.] We've also added a Facebook application, and integration with Jaiku or anything that supports GeoRSS.

MyLoki keeps your friends up to date on your location, helps keep track of where you've been, arrange get togethers with friends in your current area, and much more.

Wired: So how does your users' data fit into the formula?

Barton: The Zestimate is only going to be as good as the information we have going in, and there are lots of holes and inaccuracies. We opened up Zillow so owners could correct facts about their homes, publish their own estimate of their house's value, and upload pictures. We can feed some of that information back into the algorithm. If you say, "No, there are four bathrooms, not three," we take that as reality. It makes the Zestimate significantly better.

Designed by Margaret Hokkanen, the Team's lead real estate agent, these maps solve the problem of determining where a parcel of land for sale is located. "Some real estate web sites allow you to display land for sale in a list, but they often they cannot show you where the parcels are located on a map," explains Hokkanen. "The difficulties arise because bare land parcels have no house and often no corresponding US Postal Service address. Without a valid address, the real estate mapping tools found on other sites typically fail to display the property or put it in the wrong location."

Ms. Hokkanen states that they solved the location problem for the vast majority of the San Diego listings.
