It's from an old parable, also called Parkinson's Law of Triviality. Basically, simple things get discussed more because everyone can understand them. It goes something like this:
"If a committee designs a bikeshed, they will spend five minutes discussing the structural requirements, half an hour on the size, and the rest of the available time arguing about what color to paint the shed."
Oh ok. I wonder why he didn't just say "bikeshedding."
Spot of literary flair
It wouldn't fit grammatically.
because I'm a flashy git, but you're right to question it.
What does this mean?
