I agree 100%. With all of the content available on the web, I feel that we need to be different here and post useful, original, content.

For the serial posters, it's obvious that they're simply trying to make money and not add value to the community. As such, I typically don't give them much attention. Hopefully if enough people do the same, they will slowly disappear or learn to provide valuable content.

How the community grows will depend on what the community deems interesting as a whole and promotes (with follows/resteems/upvotes/etc).
