A lot of thoughts in this thread on what academic papers are or should be, let me give my own opinion as a person who tries to write papers.
Papers should be structured like fractals - that is, they should be "self-similar". The main text of the paper after the introduction should go into all the necessary details demonstrating the origins of the idea and proving that it has value. Then the introduction section should summarize all this, and take a less rigorous tone. The abstract should be a summary of the introduction. And then the title should summarize the abstract. If you really have a lot of technical work to do, maybe you can write a super long appendix and have the main body summarize that.
I myself probably spend as much time reading paper introductions as I do reading paper bodies, which means that probably 90% of the papers I read, I only read the introduction. I do this because I enjoy it more - I like new ideas, and the intros are a great way to get a lot of them. This blog post reads like a great paper introduction to me. It's easy to trick yourself into believing something is easy though, so an academic paper would have to back this up with an experiment.
