Something that really sucks and no one ever talks about is how the guy who created Lang-8 got distracted by the appification of everything, and created Hi-Native as an alternative with a heavy focus on app platforms and, of course, a different pricing model. It's really very poor compared to Lang-8. Lang-8 was infinitely better. But he even went as far as to shut down signups and Lang-8 has been slowly dying ever since, while Hi-Native has never achieved the same success.
