Three systems beneath network effects

I am not convinced by this trichotomy. The "Engagement" effect is just a restatement of the classic network effect, while the "Acquisition" and "Economic" effects are simple consequences of it.

He states that networked products obtain clients easier from the existing network. But this is true for non-networked products too - see the early Gmail invite system. If anything, an invite from a friend to chat with him on the early Twitter was even less valuable than a Gmail invite, that allowed you to email the whole non-gmail world, not just SMS a single friend.

What makes acquisition more effective is precisely the network effect, while a classic business acquires in a dampened geometric ratio, a networked business acquires clients much faster because those acquired through word of mouth find a much more compelling product than the early adopters, some of their friends and contacts are already there, and they derive direct benefits when more and more of their friends go online, incentivizing invitations.

The third "Economic" effect is, again, the direct consequence of the network effect: Slack can charge more for business-wide features because the product is much useful for the organization as a whole due to network effects.

There is a lot of interesting literature out there on network effects. This summary of the book seems to focus primarily on one-sided markets (the value of the platform increases as more users join). There is just as much or more fascination to be had in multi-sided market dynamics where networks of different participants and users experience evolving value propositions as the different user segments grow and change. One step further is to combine the economics of networks with analysis of the modularity of the platform functionality, and look how interface design, openness and closedness, etc., affect the evolution of the platform ecosystem. A truly fascinating topic that is more akin to biology than classical economics.

Arm wavey attempt to fuse Diffusion of Innovations with Network Effects. That could be okay. If there was any actionable (or falsifiable) advice.

Or if the layperson's telling made the source material more accessible. Like Gladwell's Tipping Point and Moore's Crossing the Chasm. (IMHO, in both examples, too much is lost in translation.)

Just read the originals. They're more concrete and clear enough.
