Marketing Copy Enhancements

• Remove the hide / show (+) button for description text for each section. Always show the text instead.
• Rewrite / simplify the descriptions text.
• Add a way to navigate to the About page from anywhere on the site.
• Consider revising or updating the About page copy. Not sure what needs to be changed but at least another look at it would be good.
