The article section, right hand side is hard to read, too small of a box, older readers may have harder time.
I love the article though, maybe some graphics in them for demonstration would add to the quality.
Real Gains* is a prime example, awesome article. So is A Day In My Life, If you could position this as a more visual site with your article i believe you can take this site to new heights, Very informative site, spent over an hour going through it.
