I agree that everyone should read this.

So, assuming the one 'user' with 500k BTC was MagicalTux, or someone close to him:

1) Gox launches with swiss cheese for security
2) Gox ignores all warning about being vulnerable, and continues to tell users they're safe
3) Gox gets hacked
4) Magical Tux's BTC gets sold for pennies
5) Magical Tux wants to roll back the transactions to get his bitcoin back

Am I missing something?
