Let me just do a wild stab in the dark here: none of these French sites are VC backed start-ups looking to get rich quick or conquer the world, but just ordinary companies happy to be making a profit.
But these VC backed companies kill these small businesses AND they later when it's not profitable enough let down their uses my closing down the shop.
Let's build a community also expects input from a community which is left in the cold. Wouldn't this make it harder and harder to form communities in the long run?
