It really just depends. I was a lurker (and occasionally commented) in a couple of Pokemon TCG groups on Reddit and I never felt a need to contribute because there was so much content already. I now create posts and comment because I recognize the magazine needs content to thrive. If there are others out there who are the same as me, and want the community to thrive, I don’t think asking them to make content if they can is too much. It’s not anyone is requiring it, but it’s a way to build and give back to your community. And it’s not too hard to do on a Pokémon TCG community, though I can see how it might be difficult on others such as a tech news magazine.
