I want us to stop talking about the sender as someone who sends messages to predefined recipients.

I want us to stop talking about messages that have pre-defined layout and content.

I want us to stop talking about recipients that must agree with each possible sender on how to communicate.

I want us to stop talking about how to find the “universal message” that is generic enough so that it can be adapted to any situation (which I believe is impossible).

I want us to introduce new concepts.

I wish that when we talk about the sender, we mean someone who publishes/broadcasts information.

I want us to talk about data streams that are published and documented by the sender.

I want us to talk about subscribers that choose which streams they wish to access.

I want us to talk about exactly what I wanted to try to explain in my last post. Imagine if we had a non-hierarchical, hyperlinked, sender-centric information system!
