Google Australia has kicked it up a notch with the way they are handling Real Estate listings. Rather than simply using maps to merely show what is for sale, it seems that Google Australia is also going to provide data such as real time changes to the property, location, etc.
Where things get dicey is in the fact that there are already resources in Australia said to provide basically the same thing as Google Au is hoping to give Australian users. In short, it would be seen as redudent.
The flip side to this of course, is worth mentioning that some people might just want to have a choice in which resource they end up using. So to this end, perhaps Google offering the advanced Real Estate details is not such a bad thing after all?
