In the mobile set-up specifically you can scroll forever and not find the bottom or the top of a page but there can still be a lot of scrolling in the browser as well. I would like to see a "to the top" option after each person's post and at the top a "To the Comments" and "To the Bottom" option as well as a footer with a link to the home page in it. These options will make site navigation easier on a mobile device and in standard browsers.
