Google have announced ‘Docs & Spreadsheets’ which is an overhaul of the original Writely interface and integration with Google Spreadsheets. I must admit I prefer the Google Docs interface and was interested to see that Docs can still publish to a blog (just like Writely).
The documentation suggests that tagging the article with keywords will be mapped to matching blog categories and that the document title will indeed be preserved in the blog entry. However, a simple test confirms that neither of these two features work as advertised (on WordPress at least). Sigh.
