Came across this post right after snapping a suggestion to improve friendlier feed for international users

This is not easily doable right now because the Hive API does not expose the language of a post as a top level value.
Also not sure we have the required volume of posts/snaps to actually make it doable. I fear too many languages will have just a handful of posts per day.

I don't know if it's already implemented somewhere, but I would like to see embedded snaps in replies instead of just the links to them

This is already implemented in snaps. But I can look into extending support to replies as well 👍
