Spritzing got me quite excited! The concept isn't new, but the variable speed (pauses after punctuation marks) and quality visual cues really work for me, in the demo at least. Don't let your inner voice slow you down!
Disclaimer: No relevant disclosures about spritzing (the reading method, at least).
Interesting. I noticed that in the first two, my subvocalization became disjointed, sounding as if each word was recorded separately like it would be in a simplistic text-to-speech program. In the 500 wpm one, this was less of a problem, and I'm not sure I was even entirely subvocalizing it. It ended up being easier and more comfortable to read than the slower speeds.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
