Again, I love how the common reaction is "Fuck you for trying to prevent theft and warning people".
No the common reaction is "Fuck you for fearmongering". Obviously everyone should be using a new password. Mt. Gox themselves made that pretty clear on top of it being common sense. But "WARNING - MTGOX HACKING CONTINUES READ INSIDE NOW" is a fearmongering title, plain and simple. That's why people reacted the way they did.
