comment Why must curve25519 shared secret be hashed?
The shared secret obviously won't be communicated to other parties. It is typically used as the key for a symmetric cipher. Why is spreading out entropy over the bits of a key important? Or it this only relevant if the key is truncated to shorter lengths (thus potentially using only the bits that have less entropy)?

@D.W. wrote "please be prepared to listen to the answers you get", sorry if I gave the impression being pedantic or stubborn. Perhaps as a non-native English speaker my comments conveyed the wrong message. I do appreciate all answers, and try hard to understand the rationale behind them.
