Search Blogs from the Microsoft Office 2003 "Research Pane"
Here's an interesting thing.
MyST Technology Partners have built an Office Research Service to access all content from the aggregation of RD blogs.
You add it to your Research Pane, with things like the Dictionary and Encyclopedia.
You can also right click on a word within Word and "Lookup" that word in a list of blogs.
What a great way to remind us that "it's just data."
