Hi Steven,
So glad that you enjoyed it (!) and thanks for reaching out to let me know.
If you liked this piece on convexity you might also like some of the "Fact File" pieces I have written, or some of the pieces I have written on "Rescaled Range Analysis." You can find them under my author archive: http://blogs.stage.cfainstitute.org/investor/author/jasonvoss/
Also, my colleagues and I are dedicated to providing useful information to investors from the perspective of former pro investors. So check back here often for more (I think) great content.
With smiles,
Jason
