"5. Syndicate your own content." Did anyone talk to you about duplicate content issues in this regard? http://www.seomoz.org/learn-seo/duplicate-content
If you're not trying to have that piece of content rank, you avoid at least one of these issues, but you're definitely watering down your link juice.
Also, for your comments in keyword stuffing, did anyone talk to you about keyword density? Keeping your density down is definitely more critical than having your most important keywords high in the copy (other than the Title Tag and H1, of course).
Happy to nerd out on some SEO or CRM stuff if you're ever interested (if you're not mad about my Google Glass post, that is (-: ) But seriously, love your stuff always. Here if you're every looking for snarky sources.
