If you are making a social media app or website, and you are going to insist on cutting posts out of the feed with a "load more" option, for the love of god, make load more push everything above UP instead of pushing the old stuff DOWN.
So when you roll back to where you left off, then "load more", you don't have to scroll down AGAIN to find where you left off.
The whole point of trying to read things chronologically, especially social media, is some people build on older posts.
