I could have written the same thing as a nerdy techie article, pointing out flaws in input validation. Do you think this would have gotten my point across? How many people would have read that article? Would it have made it to Hacker News?
Look: this is not a rant about Americans. It just so happens that US has developed most of the internet as we know it and it just so happens that most of e-commerce happens there. I'm sure any number of websites in other countries are guilty of similar sins, but you have to start somewhere.
The point is, we should start thinking more carefully about how we validate forms and store user data in that "global economy" everyone is bragging about.
