There are a couple of differences and similarities between Writely and Writeboard which are worth noting – firstly both systems allow for online collaboration – i.e. you invite others via email to contribute to the document, both allow you to subscribe to RSS feeds for the document and both allow for basic text formatting but that’s about all they have in common.
In terms of differences, Writely has a nice WYSIWYG text formatting interface whereas Writeboard requires you to enter codes before and after text to format it (i.e. surround text with “*” to make it bold and “_” for italics!). Writely usefully allows you to associate Tags with your document and to save your documents as a Word Doc. or as a Zip file!
