On the other hand, you've done a beautiful job at showing how simple OAuth can be.

That seems to be the main reason for sharing the code ("unoptimized and ugly code, walking you through Twitter's OAuth madness" and "All I wanted was a pseudo-code example of the steps involved in the auth process"). Seeing it laid out in a step-by-step piece of code helps you grok the process for either building your own independent work or using other libraries. This is pseudocode that just happens to be Ruby code too ;-) It's far too unstructured for you to realistically be using verbatim in your app.
