Infinite scroll means that as a user scrolls down, new material in a list is automatically fetched from the server. The user doesn't need to click a "Next Page" link to keep scrolling. The advantages are three-fold:
- The user experience is smoother.
- The user gets drawn into more of your content.
- Initial page load can be much faster. This is especially true for a post with a lot of comments. Responsive Tabs will load the page without the comments and then fetch comments as the user scrolls down. This saves as much as half a second in load time in our tests on a post with 150 comments.
