CFO.com is truly a great site. It is the online version of CFO magazine and has several great newsletters (which are free I might add :) ) . In fact one of their free newsletters is what has spurred this post.
The site has a list of the 100 most popular finance articles from 2004. I won't give away the top stories, but I will say that there are many very good articles on everything from what it takes to be CFO, to the importance of spreadsheets, and the impact of Sarbanes-Oxley.
A great way freshen up a class!
