Use more html5 semantics (portfolio is now a section with writing and
viz as <article>s.)
Simplify tag line
Add copyright and bottom menu to the footer.  Also, put that stuff into
a <footer> section
Reduce the number of words I'm using to describe the work of words.
The start of a carousel for dataviz pieces.
Move the carousel controls to the bottom. Also, make the banner and
header banner backgrounds the same color.
Add a banner/contact section
Add the first tortilla chart into the viz directory of pages.
