I learn lots from here, even though I've got a fair bit of experience now, others on here and elsewhere have far more.
Much of it is about there being more than one way to skin a cat, the cross wind approach being a particularly good case study.
I also learn about flying I don't do, such as mountains and tailwheel and aerobatics, which is just interesting.
All shared knowledge and experience enhances your flying enjoyment and hopefully your skill and judgement too.
