Writely lets you save documents (in the Actions menu) as Word, PDF, RTF and/or OpenOffice files, as well as to a web address. You also save within Writely.
Writely is a good tool for students – especially when they collaborate on projects. And it’s a lot cheaper than MS Word (it’s free right now).
This post was created in Writely, and the HTML copied and pasted into ecto. But you can post directly to a number of blog types, if you so desire.
