Yeah, I think that's a big part of it. I remember being stuck on things for a long time, bashing around on google trying to find something, anything that would help me understand it, saying to myself that once I figure it out, I'll certainly do a huge writeup of exactly what I needed to know to ease my pain.
Once I'd figured it out however, it seemed trivial. I must be the world's biggest moron for being stuck on it so long. Real engineers would have it sorted in a few minutes. That's why there was no posting explaining it. I was just in over my head and it was my amateurishness showing. It should have been obvious.
If I write it up, it will just show my ignorance... so goes the pathology.
