This is yet another placeholder plugin. It works similarly to tumblr's, and is a total rip off of this: http://jsfiddle.net/mrcoles/Kwsts/
I needed slight variations. This is the result.

Including the js file in an html document will automatically apply to any input/textarea which has a placeholder attribute specified.
