Load Next and Previous Posts with AJAX

I’d like my homepage to have a single post on it, with previous and next links that load the prev/next post in its spot without reloading the page.

I found this tutorial, but it doesn’t seem to work for me: https://wpcanyon.com/tipsandtricks/the-easy-way-to-make-wordpress-ajax-pagination-using-jquery/

Has anyone go this to work or have any tips?
