> Another extremely strong network effect is proprietary chat systems like ICQ or AOL Instant Messenger. If you want to chat with people, you have to go where they are, and ICQ and AOL have the most people by far. Chances are, your friends are using one of those services, not one of the smaller ones like MSN Instant Messenger. With all of Microsoft’s muscle, money, and marketing skill, they are just not going to be able to break into auctions or instant messaging, because the network effects there are so strong.

This is an interesting line, at the time AIM seemed like it was here forever. And honestly, I still have better memories of the usability of aim than modern services.

Would be interesting to take a deep dive into all the factors, was it mobile and phone text messaging that did it in?

speed of getting things out in the publics is very important, nice read, thanks for sharing
