Spritz - a technology attempts to speed up human reading speed with little to no training. If you are interested to know how it works, they have prepared a a pretty interesting article, but in short, instead of having your eyes moving around a lot while reading, Spritz keep your eyes fixed at one point, and move the text instead.
Today, I am finally invited to try out their SDK, and the first thing I do is to write a plugin for Jekyll that simplifies that process of integrating Spritz on Jekyll-powered site. Spritz for Jekyll is a Ruby gem. Setting it up should be really simple - the only hurdle is to get register with Spritz.
Do give it a try!
