You could have a A machine translated section where lessons are translated from English by Google translate or something similar. The point would be to create a lot of ocntent for that lanugage at a good but possibly imperfect level. For languages that struggle to get new content, this might be useful. If people don’t like machine translations, they can ignore the section.
Topics could be relevant to a lot of people:
How Lingq works
Comprehensible input
news etc.
