FUNimation continues to add lots of new episodes to its site and its various partners which means there's a slew of anime out there you can peruse and then follow up on with DVD or Blu-ray releases as time goes on. They've got new episodes up on their own site, Hulu, Youtube and on the One Piece Official site as well. Which episodes are you going to watch?
Free anime is always good! I saw some Soul eater in there ;]
