I'm often using Google search in Incognito/Private/InPrivate windows, so I'm getting to see all the, pardon my french, bullshit they're AB testing on users constantly. I've so far seen three distinct forms of infinite scroll (edit: on Mobile, for clarification). One is just infinite scroll with classic results in a list format as usual. The second type I have encountered is that after about 7 to 10 lines of results in typical list format, it will begin showing you everything in a grid format of squircles, where it's harder to read the text previews. The third form of infinite scroll I have seen, and in my opinion the worst, is that after fifteen or so results, it begins showing you results for a separate (but allegedly related) query, and forces you to hit a button to continue seeing results for what you actually wanted to see... and get this, the button to see more doesn't always work. Sometimes it gives an error message. (This one irritated me because I was looking at translations for a song into English, and then the results started showing translations for different songs from the same other language, but not even by the same artist -- very helpful, Google!) Currently for me, in mobile Chrome, both Incognito tabs and normal tabs display infinite scroll of the list type, where results appear more or less in "normal" format, albeit more spaced out than they were a few years ago.
