Beyond the buzz, beyond the fact that the marketing rules may have changed, every communication plan has 3 variables:
The Reach: How many people will receive your message?
The “persuasion rate”: How many people will consider your message to be relevant to them?
The reproduction rate: How many people will be willing to forward your message?
The so-called Marketing 2.0 tells that you have to maximize the reproduction rate and use hypersegmentation to raise your relevance (persuasion rate)… I believe that marketing 3.0 will re-integrate reach to get the best out of the marketing equation.
