While I agree with many things Prof Castells says, I find many of his arguments tangential at best. He tends to rely on the anecdote a little too much in this book - and perhaps on small sample research (for some of his more interesting claims - especially towards sexuality and gender).

The scope of the book is ambitious to say the least, sadly he has fallen into a trap mostly reserved for economists - namely making rash statements about the world without really going too deep into the information he is standing upon.
