I personally despise infinite scroll, at least on mobile sites, as it limits:<p>1. My ability to orient myself in the content.
2. My ability to control my consumption of the content (e.g., jump back to top, jump to end, jump to rough internal location).<p>Some sites have added navigation buttons or tool bars, but, to be useful, they must always be visible, so they take up valuable space that should be used for content. Depending upon implementation, they can also be distracting.<p>There are certainly ways that navigation options could be restored while still not significantly interfering with content, of course. If decent feedback of current location were also provided, then infinite scroll could be OK.<p>Most content breaks down pretty naturally into some smaller increments, though (pages, chapters, sections, topics, days -- whatever), so I think it typically makes more sense to present it in that way.<p>Just because we <i>can</i> do infinite scroll, doesn't mean we should.
