Many thanks MikeGeorge and Kate Morris for your input on this.
I'm certainly with you on having a quality well writen and non-spammy release written - we are on that.
But MikeGeorge (or anyone else knowledgeable about this...) regarding your "Write your own press releases on your own site and tag them appropriately" input, could you please provide details on the proper tagging?
I assume you mean tags related to http://schema.org/CreativeWork or more specifically http://schema.org/Article ?
