(…) 3 different types of products out there:
In the first case, we have something like purchasing food. Immediately that hamburger has a lot of value (you’re hungry right?) but after you eat it, the value is largely gone.
In the second case, there are products that deliver the same amount of value to you every day. A newspaper subscription is a great example of this. Every day it shows up at your door and you get the same value from it each time.
In the final case, you see a product whose value increases over time. On day one, you haven’t invested much time into it and you probably don’t even understand how it helps you. However, as you use it more and more and put more into it, the value because increasingly clear. Services like Dropbox and Evernote are perfect examples of this.
