So you can invite others to edit the document hosted on your account, and once you publish your document you can invite people to see, but you also have an option to let anyone view your document.
The beauty of this now is that I can upload a word document and publish it on my Writely account, I can then point to this permalink from a blog post…how cool is that…it’s like pointing to the permalink of a photo you have in Flickr, or pointing to the permalink of a bookmark you have in Furl.
So it can virtually be a host for your word documents (my problem before was that I obviously couldn’t point to a word document on my hard drive, and I don’t own/rent any webspace…so this has solved some issues)…Furl mentioned a while ago that they were going to allow bookmarking of personal files such as word documents, this would also solve this problem (you’d just have to re-edit your word file than re-save it in Furl).
So if you have an old blog post with content like a list that you keep going back to to update with new additions, you could substitute this list to a Writely published page and add to the list when you need to and just re-publish the page…and have a link of it on your sidebar of your blog.
This is kind of similar to using a wiki I guess…it would be good if Writely had RSS feeds for published pages.
