Not just you. I don't get the point of this either. I'm guessing it has something to do with your existing reading method? My eyes naturally jump to the first letters and tallest/round characters when determining the shape of a word.

There is an accelerated reader I played with a few years ago, based on flashing the words for you with some letters colored in red. That increased reading speed mildly, but the lack of ability to quickly backtrack defeated any gains.

Yeah it makes reading significantly harder for me. I recognize what they're trying to get my eyes to do but they already do that anyways and bolding half of everything on the page makes it harder for me to pick out the bits that matter. Bolding any part of "is", "in", "a", etc. is a hilarious choice to me.

No, you're not. I can't even read it. I can read colour-coded (i.e. syntax highlighted) text perfectly well though. This just completely shorts out my reading - might as well be hieroglyphics to me.

It does for me. The bold "anchors" make my eyes wanders less. English in not my native language, maybe that helps.

Nope. This does nothing for me.
