I’m a native English speaker, and speaking Russian and Spanish, I appreciate the effort one has to make to write in a language you don’t use all day, every day. English is a very difficult language to write in for non-native speakers, and I’m sure this tool should be a great help. The approach sounds right, the key is a critical mass of sites and editors coming together, with both seeing the rewards coming from their involvement.

I assume they’re also thinking laterally, and have different language implementations lined up, as well as thinking of how they can hook this into translation / cultural alignment work.
