If you deterministically generated a bitcoin address from a "not-so-strong passphrase", it is likely that your 0.01 was immediately swept to the other address.
You have to wake up pretty early in the morning to stay ahead of bitcoin thieves.
Thanks for the replies, Akka and Russell.
I was thinking about this more, and wouldn't a "robber" using the same passphrase end up with the exact same deterministically generated public Bitcoin address? I just typed the same even weaker passphrase ("testing123") into
http://brainwallet.org/#generator and got the same address every time (1AyFk2sxtjoG4nz35uNxcZJhLUWAymBr5B). If I had a public key collision, then where did 1JvojZKzuABZT5iCm6hKJnV7Lm1VQ8iaDk come from?
