While we could all argue between the righteousness and asshatery of what LulzSec, an off-shooting branch of Anonymous, has been up to lately, I think if there is one lesson to take away from recent events is that we should all be very, very careful about how we secure our stuff online.
Now, I'm not saying go all Boris, a la Golden Eye, but what I am saying is that personal security is more often than not the first, last and only line of defense you have against having your information visible for the entirety of the Internet to see - in plaintext. For those of you who may have had your information leaked by LulzSec, obviously change all your password immediately. For those of you who haven't, same thing and avoid the whole "Password" or "12345" business. It's just not good cricket.
