The Web is something like a piano ..

You can understand everything about a piano’s construction (the materials, the engineering, the scale lengths and tunings) and indeed those things are relevant at some level. All this information, however, tells you almost NOTHING about the essence of music nor the great works of jazz,  gospel and soul.

The Web offers a similar problem – the components and engineering describe clearly what the technical vocabulary/grammar is and can allow us to look for meaningful patterns in the oceans of data – but tells almost nothing about all the things, both great and terrible, that the Web may produce.
