would kill the community
I'm of the opposite belief. I think some communities stay dead bc there's just one person constantly posting articles with zero input. I avoid these "zombie" communities. Regular dead communities are more enticing to post in for me.
start one, and unsubscribe from the communities you don't like.
This would create even more fracturing, which is already a big problem here.
If the community is purely about news, sure. Most aren't though, and I think in that case, the poster should always be the first ones to strike discussion.
