Sure you know about blogs, wikis, tagging, and of course MySpace, but can you explain what exactly Web 2.0 means? Where is the line between Web 1.0 and Web 2.0, and how will we know when the next version emerges?

The article does an excellent job of putting the term and the applications that fall under it into perspective and shows how Web 2.0 tools are different from their very similar predecessors. You can read the article here.
