Talk:Strategy for Information Markets/Network Externalities/Two-Sided Platforms

shape of the curve
On the one-sided network page, there's a bit about "notice the shape of the curve ..." Notice some things about the shape of the curve: Should this be repeated/modified for two-sided, or assume it's OK sine it was already done 1-sided? TDang (talk) 16:50, 7 October 2010 (UTC)
 * 1) When expected quantity is low, actual quantity demanded is zero. This isn't always true in products with network externalities, but often can be. Nobody wants to pay $50 for a telephone if there's nobody else on the network they're interested in talking to. We'll consider this a typical case, and look at exceptions later.
 * 2) Quantity demanded is increasing. The curve for quantity demanded is sloping upwards. As more people join the network, more people want to join the network.
 * 3) Quantity demanded is increasing at a decreasing rate. A bigger network is always better, but it doesn't keep getting better as fast. When 20 people have a telephone, a new person joining the network is a big deal that increases the value of the network a lot. When 2 billion people have a telephone, one more person joining the network doesn't noticeably change the value for most telephone users. Since the value of the network doesn't change very much, it doesn't influence many more people to demand the product.

shorthand as one-sided network
I just removed one possible shorthand for two-sided platforms. I'm concerned it may be misleading, and want to pull it out pending verification. TDang (discuss • contribs) 15:36, 4 October 2011 (UTC)

social networking and mall
I removed this section. It might be correct, but it's confusing in its current form. As near as I can tell, it's trying to get at the idea that one side of a two-sided network can be its own one-sided network. I believe that's true, but it is still confusing and needs a better model, or to be left for more sophisticated development later. To replace one of the simple points there, I added a bit on shopping malls (that could probably afford to be expanded). TDang (discuss • contribs) 16:44, 4 October 2011 (UTC)

more on dynamics and critical mass
Need to cover those topics more in-depth. TDang (discuss • contribs) 03:37, 13 October 2011 (UTC)
