I'm sure it's a good blog post for the right reader, but for something to land on HN front page, I generally look for either:
1) a story that, while specialized, reveals something accessibly technical and interesting to a semi-expert crowd, or
2) explains something at a sufficient level of expertise/detail that people not in the middle of it can grasp and apply to their own knowledge.
This story seems not accessible to the general reader. Or it reads like someone's private notes. I think it needs a level of abstraction or summary to be accessible to the readership here.
