For a simple text editor for longer articles I am looking for advice and inspiration on programming/designing a minimalistic and modern textarea (which does not necessarily have to use the tag) accompanied by a save button. I thought, there should be plenty of "25 textareas you can't miss" articles out there, but so far, I have been surprisingly unsuccessful in finding them.
What is the state of the art? What is different when designing for mobile? What pitfalls should be avoided? Where can I read more?
EDIT
I have been considering rich text editors, too. They however seem too heavy in many cases. Maybe there is a subclass of "not so rich" text editors, meaning wmd and alternatves? I will definitely look into http://sixrevisions.com/user-interface/rich-text-editors-for-2010-and-beyond/ .
