Sharedcoin transactions on blockchain.info lowered to 0.0001 BTC per repetition. On average 1.8 unique participants are joining in together each transaction, so over several repetitions there is a very good chance your transaction will be directly mixed with other users not just the sharedcoin server.
When did that happen? That's a major change that deserves a large announcement. Are they using BIP32 to derive the new addresses?
It's just for Sharedcoin transactions and not BIP32 yet but I hope that will be available soon.
