Now here’s a switch… Penzu is an online blog-type service — that you can keep private! All the other blogs in the world are out there so you can share your thoughts, but Penzu lets you create a private journal for your eyes only, though you can choose to share with others.

I’m not sure what type of business application this might have, but I love the notebook-paper graphics. PC Magazine gave it props for being some of the best free software of 2009.
