I have just experienced that recently. Setting up was easy and there was no problem at all blogging from within Word. If you don’t know such feature exists in your piece of expansive software just purchased read this.
If you are writing a document with multiple use then blogging straight from Word is great. For me it’s very likely that I may have to amend the codes behind adding class to float an image or adding hot links of images from Flickr etc.
I’ll wait when there is add-on for Word available such that I could amend codes behind my blog posts.
