It is indeed great to know that Orkut is still alive and people still use it... above all Google is still adding functionalities to it. The latest one being adding maps to your scraps...

Once you select an address, your scrap draft will look like this:
Just post it and your friend will see the map you added. If the map is clicked, it loads the Google Maps page for that same spot, so your friend can further explore the area, check Street View photos, and even find public transit, drivingor biking directions to get there.
