Use jquery to turn form labels into placeholder text

[edit]Nowadays the support for placeholders is quite strong, so I would recommend against this approach. Kept only for posterity.[/edit]

Check out my nice new jQuery plugin (with drupal module included) at http://www.dhmedia.com.au/blog/nice-placeholders-jquery

What does it do? It converts form field labels into dynamic placeholders (the kind that disappear when you click on the field and come back if you don't enter any text).

While it's not a HTML5 placeholder, it does do a grand job of simplifying the process of adding placeholder text especially to drupal web forms.
