Web 2.0 is made of ...recycled tech blurbs

We had a client banging on about Web 2.0 the other week – how it will be the next big thing and now is the time for some true Blue Sky thinking!
Unfortunately I haven’t got a clue what Web 2.0 is. Does it mean anything? For help I turned to The Register and got the following answers. Here's a selection of what their readers thought it meant:
