I live in France too, and all my friends have heard of it, and some even use it regurarly. I've used it several times, and the people I've travelled with came from all backgrounds, so I wouldn't say it is only for 'techies'. For passengers, it's a really cheap way of getting a ticket to somewhere, and for drivers, a way to pay their trip (gas, toll, etc.).
