I understand why you wanted to write all this, but you didn't seem to put much thought into whether your intended audience might want to read all of it. Short posts with simple topics are much easier to commit to; a long post can be forgiven if it has a strong hook at the beginning and a simple (could be summarized to a ten-year-old) structure to the different parts. This article seems to have neither.

For that matter, you need to include a summary break in your post (it's one of the options at the top of the Edit window) so that you don't infuriate everyone who'd like to scroll through the recent posts and see what's new.
