Infinite scroll has become a standard feature in many web applications. Twitter and Facebook are the ones I use every day, but it’s also in a ton of Tumblr themes and Cargo Collective sites.
I feel WordPress themes has been slow to adopt infinite scroll- but after adding it to my site over the weekend I understand some of the complications.
(The Infinity Pool comes close, but it’s not as cool cousin, Infinite Scroll. CC Image. )
Unlike Tumblr or Cargo Collective, WordPress (.org) users can use plugins to add all sorts of javascript to posts. On my site Syntax Highlighting is the main culprit (which I use to display code snippets), but many others have social buttons or lightboxed images.
When infinite scroll pulls in additional posts via ajax, it doesn’t load the javascript code from the header or footer of the post that might be needed to display js content (e.g. social buttons, formatted code, etc) properly. That puts theme authors in a bind. Infinite scroll may be a better end user experience, but it’s going to lead to more support requests during theme set up.
However, if you don’t use much javascript in your post content, or if you display excerpts on your index pages rather than full posts, I’d suggest trying it out.
Ben Balter made a fork of the popular Infinite-Scroll plugin which is excellent. It’ll hopefully get merged into the .org plugin version soon (which I can’t recommend using in its current state). If you use Ben’s version of the plugin you should be able to set up infinite scroll for your theme in just a couple minutes. You can also see it in action on his site.
I’ll also posted a tutorial about how to add Infinite Scroll to a theme without a plugin.
