Indeed, networks are a hostile environment. I think most people who would be on HN understand the basics of programming for the public.

you'd think, right? :)

But you would be amazed by the amount of crazy stuff that we see here at Anchor from Web Developers who we think know better.

Obviously, it's not the same for every web developer, but reminders of just how volatile the Internet is in generally can never hurt.

I am guilty of considering HN members as being more educated than average, I admit.

come on, if you're making a web app and you don't know about stopping injection, you should be an intern, not a developer.
