hello: as a screen reader user i don't think the list idea would work at
all after  all lists have fixed numbers of items and when the screen reader
moves in to them they are told how many items so it gets some what
distracting to here list of 5 items when there might be 10 20 or more
items. . i do like the button that says load more  but don't make it
invisible  as then when the keyboard only user moves to it they will not
know ware they are. i find the way that twitter does it works for me i
don't find my self not getting the next load if i navigate with the twitter
keyboard shortcuts and not the screen reader. maybe a  spoken  alert if it
takes to long that says "loading more content " would be help  full. thanks
