@Nagaram I like #Duolingo too. but it is because it actually does teach me languages!!! Using just Duo I was able to get by in Italy, even tiny towns in Sicily where nobody spoke English!
I can read and understand many posts on Mastodon in German and even make short simple replies.
And although I could already speak French like a 12 year old, Duo has taught me many business and computer words and improved my spelling!
So keep it up. Let's all get multilingual!
