For one, this blog post is being written from Word 2007 with its new Blog Publishing system. Very cool indeed, but this feature does need work… CS Photo stores need to be supported as do post categories. If the category does not exist then it should create it.
That said, I have found the whole thing to be pretty stable as a product.
Right now, Outlook 2007 is looking very cool as it syncs up all of my IE7 RSS Feeds, no more requirement for Reachout or any other RSS Reader in outlook! More soon.
