Four types of Content Loops

Break it down by:

1. User vs. Company created content
2. User vs. Company distributed content

Given this we have four types

1. UG, CD - SEO
2. UG, UD - Social
3. CG, UD - Social
4. CG, CD - SEO

Pinterest has both UG-CD (via SEO) and UG-UD (via social)

Primary constraint - cost of content generation and return per piece of content.
