Il n'y a aucune obligation d'ecrire quoique ce soit si vous n'en avez pas envie... Vous pouvez juste parcourir les ecrits et reagir a quelque chose qui vous interpelle en particulier... Ce que beaucoup d'utilisateurs font je pense. Evidemment il faut que des sujets initiaux soient ecrits, sinon comment repondre au neant ? ;)
I am sure you have interesting stuff to share! I am also part of the 99% silent majority: I've posted to reddit only once in 7 years! The feeling of not having anything to share is merely psychological and a force of habit. Since we never post, we never think about posting. Other issues are shyness and perfectionism. I've been trying to post one thought per day here to try and change my mindset. It doesn't have to be perfect, nobody knows me here, no up or down votes.
In real life, we have beers to help us speak more easily... not on social media! :) Most of the people who speak don't have anything to say either. That's the beauty of it. We don't go to social spaces to learn, but more to connect. I'm glad you wrote your message!
