Oh, for example, say you meet some dashing devil here in Paris and he gives you his carte de visite and you've agreed to meet for un apero on Monday.
Well, once back at home in your jammies, you log on to your computer and of course you Google him. That's kid stuff. And if you're more advanced and more curious you check out his neighborhood with the aerial view on pagesblanches.fr or Google Earth.
Goody! Now Pages Jaunes shas added a new feature for the infinitely snoopy that actually allows you to see the facade of his building. (You of course want to be sure it is a building of tres grand standing, no?)
Part of me finds this really fun and part of me finds this totally creepy.
