Web 2.0: Browse And Interact With Your Friends On-line

Imagine you just know where your friends & like-minded people are.
You can see what they see & discuss the same things. You visit a
web page and instantly hear what a group of your friends, experts and
other web users say about this site, page or topic. As you browse you
discover new sites, ask questions, get help & recommendations, read
& rate reviews and ideas. You might even help others and speak-up
your own mind.
