59 points of consideration. Wow. That's a lot of soap boxing.
This article would be a lot more helpful with explanations and code examples.
Agreed.. Even linking to sites with forms that demonstrate some of these points would be worth while.
The list also assumes you are using every tool in the <form> toolbox, though that might of just been for completeness.
even better would be a web app that took form html as input and spit back warnings and errors. it wouldn't be able to complete the whole check list, but at least you wouldn't have to look at 59 items every time.
