in response to the query about uploading documents to a blog, as I see it, there are a couple of choices.
a) you can convert your doc to a picture and then upload it, as you would any image.
b) the other is to use some kind of 3rd party site and then create a post with an embed code. I have used Scribd.com in the past for this. I've pasted an example below of how it works.
(The reader can view the doc full-screen, or print it or download it according to his/her needs.)
