Great exposition on the subject. I decided a while ago that: 1) I was going legit with my purchases and 2) I hated optical media, which has led me to the point of purchasing all audio and video media I consume through outlets created by Apple. I am on the same page as most of the general consumer population, I think.
So yes, Apple is charging 30% of subscriptions within their applications, same as sales happening through the iTunes system. Because, frankly, they are growing your potential market, as a music publisher, a magazine publisher, or a book seller. They are doing what you could not - fixing the barriers to consumption, and barriers to purchase, for your product.
Frankly, you could not have done this yourselves. And if you’d managed to hire the designers, developers, managers and consultants to create this model for you, it would have cost more than the gross amount of the 30% per sale that Apple is going to charge you.
Did the Internet community peak at bookmarks? Asked in a different and perhaps more complete way: just as technologies like RSS and email in their purest forms are hard to beat even as technology marches forward, what better technology exists to keep track of information on the ever-expanding Internet than bookmarks? Taken a step further, what better way to share the bookmarked information than a site of your own? As such, I‘ve been reading, which is why I write now.
Working in and having a passion for libraries, I am struck by the fact that the way bookmarks work in the physical world is not directly analogous to bookmarks in the digital world. Bookmarks in the digital world are instead like dog-eared pages or highlighted passages; if you think of the Internet as a single tome, that is. In any case, anything that moves you to deface a book should probably be shared or become immortalized in some other way than just a reference for a future version of yourself.
