Pinning posts to the welcome page is vastly preferable to trending as an exposure mechanism to content via that vector. I'm not sure that detailed discussion of Steemonomics isn't a bit dry or potentially too confusing for neophytes, but it's better than trending IMHO. @vandeberg's ability to clearly explain complex issues in layman's terms is well revealed in his latest post, and it's comforting to me that someone so intelligent and rational is filling his boots in development.
