I've been working on a sort of MyBitcoin competition - bit-bank.org. It's quite similar to MyBitcoin, however I certainly hope it doesn't attain the reputation MyBitcoin has.

Quite a simple interface - you're able to deposit / withdraw bitcoins, send them (instantly) to other Bit-Bank accounts, etc. Registered users are also given a custom URL - such as bit-bank.org/user/seeARMS for my own - which simply displays your BitCoin address.
If anyone has any opinions / feature requests, I'm all ears. I aim to be as open as possible to avoid the inevitable trust issue.
