Add a filter by language. I checked the "Educational" section and I saw posts in English and Spanish. That is not a problem for me [Hi from Argentina!], but I can only read a few more languages and with a decreasing level.
I actually have a filter by language it's the last one in "Filter By" list. The website does try to guess your language based on your IP, but you can change it and it saves your setting.
I didn't notice the filter list can be moved. When it moves, I expect a < and > on the dices or a scroll bar at the bottom. But I think both methods are considered "old" design now.
I got automatically English and Spanish. I thought it was a coincidence that I saw only post in those languages, but now I see there are more posts.
[Side note: I got one in English about telling direction to the 911. https://cosmos47.com/post/how-should-you-give-your-location-... Relevant xkcd https://xkcd.com/783/ People here is more use to a hard address instead of landmarks and turns.]
