Some very clever individual has recently released a decentralized tumbler for obscuring your transaction paths called JoinMarket. Details can be found in this post: http://www.reddit.com/r/joinmarket/comments/358dlv/joinmarket_released_on_mainnet/ and on /r/joinmarket
Worth taking a look for those looking to avoid trusting (expensive) third party tumblers.
This sounds promising; you should spend time actually writing out a detailed post explaining what this service does. Trying to win us over on throwaway accounts with bad grammar doesn't exactly inspire confidence:
