better than nothing?
Of course Wikipedia isn't perfect, nothing's perfect. Everywhere you look in the world there is injustice, and journalists make a living from being outraged by it, as if we (humanity) had a choice between doing things right and doing them wrong, and we chose to do them wrong.
But that's not the way the world works. We invent things at random all the time, some are good, some are bad, we usually don't know which is which when we invent them, and on the whole the ones that don't work fall into disuse. Could anyone really claim that the world as a whole would be a better place without Wikipedia in it?
