Blogging in 3D?

In last Monday's The Australian I was interested to read the article "Internet giants take on battle for Earth in 3D" (November 27, 2006, page 3). It explained how "Two internet giants have embarked on a race to become the first 3D cartographers of the world".

"As the rival schemes develop, buildings will become interactive, enabling users to virtually enter them, obtain information, buy goods inside and talk to other cyber visitors. Eventually, landscapes could be included."

"The move may bring about a transformation in how people use the internet. Instead of relying on traditional search engines, in which they enter words into boxes on screen, users would be able to navigate the world using a virtual replica."

This made me wonder about the future of blogging. Will we one day virtually enter one anothers houses and wander around having a chat?
