>swing them moderately (not too little, not too much)

Just had to point out this delicious tautology.

Anyway, I don't think you can sum up correct running form in words, or if you can then it's not useful. My advice would be: keep your tempo (steps/minute) around 170-180, do ankle mobility work and hip/glute strengthening. A high tempo lessens time in air each stride and thus velocity when hitting the ground, lowering impact on joints. Ankle/hip/glute work will stave off most muscular imbalances, which are the root cause of many form problems.

Just had to point out this tasty contradiction. ;)

Au contraire! My tips aren't describing good form, as much as describing the conditions that lead to good form. A subtle but important difference.
