Help Google adding correct street numbers in maps

I stumbled upon a nice way of distributing tasks implemented by Google. It's about street numbers, which in most of the navigation applications are problematic. Google is trying to fix this by giving you this refined CAPTCHA mechanism:

Each time you post to a blog comment you get this CAPTCHA (if you get it).

I imagine that these images are in a database which associates them to:

* street
* gps coordinate
* direction (left/right)
* ...

I completed with a wrong number and got no complains :)

Happy mapping Google!

Right, but that doesn't mean they'll blindly use your incorrect number - it was close enough (2-3 digits) to what they expected, and there was the second part to validate. Now increase the sample size to a few hundred users, and voila - you have a statistically accurate answer :)
