How can you describe exactly what Web 2.0 design is?

Hi,





When somebody is telling you "Your website should have Web 2.0 design" what does that mean exactly? What are the characteristics of this type of design? Can you provide us some on-line documentation or links to websites that have this type of design?





Thank you in advance.
