This has got to be really a preview of the Web to come. For you cutting-edge readers and Web 2.0 developers this may look like nothing new or for which to roll your head over, but for whoever is not a geek, this is really the coolest preview of the Web to come (the so-called Web 2.0)I have seen so far.

This free online application is nothing but a great, smart mashup of two open services available on the web. One is Craigslist, the popular online classified ads free service which has been taking away tons of business (and money) from US-based newspaper classifieds. Craigslist offers a no-frill interface accessible according to different categorization views and very straightforward to use. The other one is Google Maps, a free interactive mapping and visualization service providing direct access to zoomable maps or satellite views of the entire planet.

Now, when you extract from Craigslist all of the apartment rental classifieds and mix them up with Google Maps you do get an amazingly useful visual maps of who is renting what.

Not only.

Here is my illustrated review of this great working prototype of the web to come.
