I think it should be a fundamental concept to Steem that, in an ideal world, would be optionally done by the blockchain itself.

With the necessary changes to curb exploitation, I thought this suggestion was great too!
This would make many users realize that interacting on this platform is incredibly important and that it can even be a little lucrative. Then "everyone" wouldn't feel "forced" to post articles at all costs, no matter how poor their content. Maybe the latter statement is a little unfair, but that's how it often feels with the "new generation" of Steemit users, unfortunately.
