jQuery/Ajax form validation

[eluser]slowgary[/eluser]
Also, there are several ways to submit a form (like pressing enter). If you remove the form and instead opt for a bunch of inputs and a button, your "form" now requires JavaScript instead of just benefiting from it. It also becomes less accessible because it requires a 'click' on the button (most of the time I tab and hit the spacebar on buttons instead of clicking). Additionally, your markup will likely never validate.
