Web Word Processor

There are a number of alternatives for good 'ol Microsoft Word, and one of those that I've tried recently is Writely. Writely is entirely web-based - no downloads or plugins required. In addition to one of the best web based WYSIWYG editors I've seen, there are a number of integrated collaborative functions to allow small teams to work on documents together, and it has import/export functionality to and from Microsoft Word files as well as publish to PDF.
