Speed reading using RSVP

I discovered RSVP today (Rapid Serial Visual Presentation). It's a method of increasing your reading speed by flashing the words sequentially in one place.

This speedreading test measured my normal reading speed at 466 words per minute, but with RSVP I found it comfortable to read at over 600 words per minute using the Reasy firefox extension without any training. I suspect I can probably increase that further with practice.

Aside from reading performance the other interesting feature of RSVP is that it requires hardly any screen real estate making it really practical for portable devices.
