Ooh I love this
Is there a community where there’s daily interesting words, either from old timely English or just plain uncommon even in today’s English?
That’s how I learned English way back then, on top of having an awesome teacher encouraging it. She would ask the class to find a couple of words or give some weekly, have us write a couple sentences using it and she would correct us.
To add to what have been said, instead of QR code for users, have it for communities instead. That’s what Lemmy/threadiverse is more built around.
