Web 2.0 What does it really mean?

When I saw Web 2.0 written for the first time, I took it to be a W3 standard for web authoring. Call me crazy… but that’s what I thought. Another standard. IEEE-like. Then I started seeing it everywhere …as though the world cared. 

A little later I realized it’s about not only authoring stuff to be read on the web, but creating stuff for people to interact with. And it would make it easy to label what you’d prepared for interaction so that others could find it and contribute (write on it!) too. Think bookmarks gone global. Think defacing public property, oops… I mean, participating in the creation of encyclopedia entries. This isn’t helping much, is it? Okay, try this video: 

Now do you know what I mean?
