I'm curious about the unusual in-sentence double-spaces in the example paragraph. Is there a technical reason for them?

EDIT:

I see now that they are not double-spaces, but that I was being confused by the editing unit of a word and its following space. I'm impressed with how well the tool localizes where a change has been made, but I wish more common editing facilities --- especially navigation across word boundaries with the arrow keys --- could have been preserved.

Hi Jason,

Thanks for this feedback! We are an open source community, and this sounds like a great project for a hacker to pick up. I'm making a GitHub issue for it now. Thanks!

On Opera (23.0.1522.43) there is a rather painful redirect loop rending the site entirely unusable.

Technical issues aside, this is really well done.

Same thing on Chrome 35.0.1916.153 on Windows 8.1. Shame, it looks really interesting but that totally put me off.

Thanks for this note! We are looking into it now.

Also broken on Chrome 35.0.1916.153

Thanks for posting this! Checking it out now.

This looks great. I was definitely engaged by the home page and found it fun to read -- maybe a number-of-edits tracker on the side so you don't have to keep re-counting how many errors you've corrected?
