Platform types?

Here's an attempt at a high level categorization of platform types (really early thinking on this):

• One method is parasitic. Where the services promote the development of new services that run outside of the core offering.
• The second is participatory. Where the services promote the development of new capabilities within the core offering (enhancing it).
• A final type is symbiotic. Where multiple platforms leverage each other to create a combinatorial platform. Each platform leverages the services of the other to enhance themselves.
