Sites like Facebook do this, and I have no idea why.
Want to "Create a page". Well there's a link at the bottom. But if you scroll to the bottom of the page, it's going to load more content and push the link down.
I just tried it, and the page reloaded 15 times before I gave up... never did get to the link.
This is clearly unintuitive, but at least it exists.
You could mitigate this but it would be useful to see what benefits people think infinite scrolling introduces and (if there are any) see if there is a solution that gives the same benefits with fewer costs.
Maybe some hybrid 'paged' infinite scrolling where you can keep going but clear pagebreaks are displayed which are mirrored in the browser history.
Unfortunately, I had to custom roll this solution. I started on a plugin but making it universally usable for a number of use-cases is a bit time consuming.
I just check it out once every 2 or 3 days for a quick laugh and eventually I stumble upon some images I've already seen, which is when I close the site.
