The pun in “Mediapart” refers to “participation”, but also to “à part”, French for “different”. Difference lies first and foremost in the price: Access to the site requires a 9€ (£7, $13) monthly subscription. Quality journalism must be paid for, they say. These subscriptions will feed forty journalists, many of them coming from major traditional outlets.
The barrier is also supposed to allow for more qualitative contributions. Trolls must all be greedy, then.
