Canadian real estate website Homezilla have created a 'TweetLens' on Canadian real estate. The 'TweetLens' is a Google Map showing you the most recent 20 real estate related tweets made in Canada or for any location in the country.
You can choose to view Tweets for a specific location by using the built in search option or you can choose major Canadian cities from a drop down menu.
Tweets are shown on the map with map markers and also appear under the map. If you roll your mouse under any of the Tweets below the map the corresponding Tweet will be shown on the map. If you choose the 'auto update' option the map automatically updates the Tweets every minute.
