[psykotic]

Great idea. But as a fast typist of both prose and code I found the interface nearly unusable. Please make it behave more like a normal edit box. I never had any idea of the location of my cursor. The lack of alt-backspace made it unbearably slow to correct errors. Auto-skipping whitespace makes it tougher to rely on my habits where the key strokes for indentation and line breaks are a natural part of the flow. And if you're not going to make me type the comments, just delete them from the text entirely so I can more easily scan ahead.

Here's a straight-up bug: I had to turn off a Chrome extension (Type Ahead Find) that I use for incremental search. It was intercepting key strokes that were supposed to go to typing.io. That hasn't happened with Ace and other canvas-based text editors. My friend also mentioned that it didn't work with his Danish keyboard.

Beyond these annoyances with the implementation, typing the C code from Redis reinforced how difficult (and frankly infuriating) it is to spontaneously conform to an unfamiliar coding convention. E.g. no spaces in "while(1)" throws me off completely because my brain is thinking "while 1" and my fingers translate that into my customary "while (1)". If you want this web app to be relevant to real-world programming, you need to let people upload their own code samples.

For even punctuation heavy, syntactically gnarly prose, I can average 140+ WPM without much effort. Typing.io put me at around 100 WPM for the first few sections of the C Redis lesson. I'd say I'm good for at least another 15-20 WPM if the environment wasn't so utterly alien.
