The use of up-front efforts to bootstrap the network: One critique of subsidizing networks in this way is that it's like "selling a dol lar for ninety cents." Yes, it would be ideal to be able to grow a network with positive unit economics from day one, but sometimes it's just not possible. Or it might be too slow. A new networked product is better off taking on the risk of subsidizing the network up front, and then improving the economics over time.

Disruptive technologies are dismissed as toys because when they are first launched they "undershoot" user needs. The first telephone could only carry voices a mile or two. The leading telco of the time, Western Union, passed on acquiring the phone because they didnt see how it could possibly be useful to businesses and railroads-their primary customers. What they failed to anticipate was how rapidly telephone technology and infrastructure would improve (technology adoption is usually non-linear due to so-called comple. mentary network effects). The same was true of how mainframe companies viewed the PC (microcomputer), and how modern telecom companies viewed Skype. The next big thing will start out looking like it's for a niche net

The solution to the Cold Start Problem starts by understanding how to add a small group of the right people, at the same time, us-ling the product in the right way. Getting this initial network off the ground is the key, and the key is the "atomic network"_ the smallest, stable network from which all other networks can be built.
