Writely, an online word processor, is causing quite a stir at the moment. Why? Well its easy to set-up, fast, free (in beta) and familiar to anyone with even a passing familiarity to MS Word. With its WYSIWYG editor, you can change font and font size, spell check and even insert images. Things get even more interesting when you find out that Writely can be used as a collaboration tool - users invite others to collaborate on certain documents via email.
