I agree with that @ronni... "quality content" doesn't necessarily mean "long." A short post, a photo, a clever political cartoon-- these can all add value.

Authentic dialogue on content-- on different content-- adds value. Engagement adds value.

Someone relentlessly posting "nice, please follow me and upvote my latest post" over and over and OVER again adds nothing (expect for a little "dust" to the blockchain) but DOES have the potential to drive out better content, if allowed to go unaddressed. In a sense... it's almost like a variation on Gresham's Law (bad money replaces good)... in this case, we allow the "lowest common denominator" to dominate.
