Last week someone asked me about putting word documents in VSTS; now Buck Hodges talks about installing a diff tool for .doc files: http://blogs.msdn.com/buckh/archive/2005/11/28/497556.aspx
Currently playing with the diff tool (for the moment it is somewhat slow, but hey, I gave it two different documents to compare, and not the smallest of them). I'll report back when I've been using it for a while, I'm going to put all my articles and stuff into VSTS and see what happens...
You might also want to try www.foldershare.com, it's great for sharing stuff between your different pc's, or for sharing pictures with those you love...
