- Consumer as communication channel: viral in its purest form just carries over a many to many channel an essentially one to many message from a business to its audience.

- Consumer as message author: recommendations and referrals are where the ‘consumer’ is already an ‘employee’ of the business, effectively working for the Marketing department and generating the message in addition to caryring it.

- Consumer as a transaction participant: where the business has found a mechanism to engage the consumer in more than just passing a message, in ‘closing the sale’ (one more hat for our poor ’sumer – now he also works in the Sales department), processes orders and (why not) takes PayPal payments.

- Consumer as co-creator of the product: from participation in product design R&D with feedback, ideas and recommendations, to UGC, particularly where the ‘product’ is the message he spreads. Two more jobs: in the R&D and in the Production department of our business.

- Finally, consumer as Investor: already an insider of our business, he confidently buys our stock (and recommends that, too). Clever companies find ways to engage them even better in the share ownership through dedicated schemes. (I think I coined the ‘investomer‘ word back in ‘98-99, but can’t be sure, I see evidence of usage at about the same time elsewhere).

This convergence of stakeholder roles is perhaps the most significant aspect of the ‘2.0′ phenomenon and the radically new business and economy thinking. Companies whose visionary management are able to view the world in this way will become leaders in their field and set examples for the entire global economy.

Needless to say, the most interesting ‘things’ to watch in the startup and venture space are business models that harness one or more (the more the marrier) of the above modes and roles.
