Bionic Reading showed up a few times in my Twitter feed, but I’ve actually been using it for awhile in my mobile RSS reader (
Reeder, and yes I inexplicably still subscribe to RSS feeds.) I can’t speak to the purported improvements in cognition, but I do find I read a bit faster and it’s a bit easier to read long passages for long periods. When I sent this to Kyle he said “That seems clever and I might hate it”, so it’s a win-win for me.
