A while back I had learned about some Google Hacks geared toward software I had installed. I experimented with them to see what was vulnerable and thus learn how to protect my own sites.

What surprised me the most was that when I would email the site owner their username and password, they often didn’t care.

I even ran into e-commerce sites where their customer database, including complete credit card information, was completely exposed.

Everyone who builds a website needs to learn about these things.

Ryan Steyn: It is not jail time to clicking on a publicly available Google link. (On the other hand, URL manipulation such as “sql injection” is.)
