Also creates a confusion that algorithm profiteers love, where before you could know a post you saw would be page 1 today and page 2 tomorrow now the homepage of every app is absolute chaos so you have to spend hours searching for something specific or you're just always seeing exactly what they want you to see (to increase engagement or whatever instead of any sensible order)
I have always hated infinite scroll because it becomes way more difficult to understand the index of a search result or piece of content. For example, if I know that each page of results contains 25 hits, then it is easy for me to see which one is the 25th hit, and then which one is the 26th one (first one on the next page).
I don't mind that the order of search results might be shifted around over time, and I understand that there is some profit motive to inserting tangentially relevant or sponsored hits, but I really wish that there were an easy way of knowing what index each result has.
This grew out of a funny little habit I sometimes have where I like to pick a random number and see what search hit that corresponds to. It becomes too tedious with infinite scroll.
