Writely allows you to create new docs from Word but not insert into docs
LATER: It was not the Writely folks, it was Christoph Janz of CalendarHub.
The Writely folks (thanks!) left a comment on my Writely doesn't read Word docs post. Yes you can create NEW Writely documents from Word documents but you can't insert Word documents into EXISTING Writely docs. I am sure that's an oversight that will soon be corrected!
