Hi Laure,
And I wold like to add, revamping the SDN to a gamification site SCN, the community really lost all its standard. Antecedently the documents were posted only after the review by moderators, and now anyone can post anything, which really makes this place only a tomentum. Instead of utilizing the site for sharing/referring the knowledge and solutions, gamification really 'coerced' the users to spend time over ineffectual travel blogs, chats & jokes. I often see my associate outlays time over 'Coffee corner', previously he had published so many utile documents in BW. And he claims he acquires more point in such 'corners' without any arduous effort. For such recreations, I believe we have many other websites and its high time, the SCN should keep a line of distinction between useful contents and these point blooming gamifications, in order to comply with the touchstones. P.S.. I admit it only when I talk to myself, that I have also made so many points via gamification, 
Thanks and Regards,
Abyson Joseph
