There are a lot more places than just the US that use "at" to refer to a location. Why not just release to anyone who wants to use the English-only app?
We did release it in all of the english speaking countries that we could pick out of the list. The app actually has canned messages as part of the functionality, so I think it'd be pretty rough to use in any country where you'd likely meet with non-english-speaking folks. So question 1) Is there an english speaking country we missed? 2) Are there enough ex-pats-who-meet-with-mostly-english-speakers that you think it'd make sense to launch without native language support?
