I see “network effects” cited so frequently as this impenetrable fortress, but… literally every site that now has “network effects” had to fight them to exist, so it seems kind of odd…
We talk about exponential growth a lot more than exponential collapse. Historically, social networks collapse as quickly as they grow. Even mighty Facebook recently hit the peak, and in their most important markets the network effect is utterly collapsing.
When LI started, it didn't have much competition so it was easier.
Network effects is not an impenetrable fortress. It just means your product has to have a really good reason for people to switch, and I dont see anyone in the work network space doing anything really better than LI. I wish someone was.
