I have been considering this since the password-hacking spam incident.
I had used almost the same password everywhere even at a bank account, so it was a frightening incident. I wasted so much time to change all the password to make sure everything is safe.

The other reason is quite hard to explain, but it is nothing compare to the first reason.

But I want to say thank you to all the visitors here.
I could not make myself to delete my pictures because of all of your lovely comments.
Thank you so much!
