Some years ago when Google launched its Knol project, it seems to me that they touted it as a place where authoritative authors could post articles on subjects in their field of expertise. Knol was phased out after Google+ was launched. But it has never been clear to me why an expert in any field would want to be associated with Google+. Instead, I think that it will mainly serve as a new doorway into the SERPs for spammers like the OP of this thread.
