Thank you for making this, I was planning on doing it just never got around to it. With that being said, here are some links that will be helpful for people getting into the manga. If you don't want to start reading from the latest Arc I suggest you start with Arabasta arc, that's if you are unable to deal with starting from the very beginning. (You will miss a lot if you don't start from the beginning but the best action come from Arabasta, Enies Lobby, Skypiea)

Oh yeah, since it took Anime's or AMVs for me to get into most of the manga I read I figured that's how most people got hooked on Naruto/Bleach so here are some good AMVs:
