Intuition
It feels like the greedy algorithm is almost good enough for Erdős–Straus, and the gap between four terms and three is where all the difficulty lives.

The Sketch
Post a math idea before it's finished, like a conjecture you can't prove yet or a pattern you can't explain. Anyone can post here. Everything here is public. People can comment, and anyone can ask the Network about a sketch to get help making it rigorous.
Only sketches whose author is asking for help making the idea rigorous.
