> I think the thing I dislike about Duolingo is it sort of catches the casual person into a trap by misleading them into thinking that by using this app they'll learn another language

But does it? I have learned other languages using it casually (one lesson a day on average.) Enough to read text in those languages and understand basic conversations. It is not getting you to B1, but it is getting you well in to the A's. If you do any type of additional study on the side, you can easily get to B1.

The main issue with Duo is the quality of the courses. It varies a lot. Some of the user maintained ones are fairly poor. Especially for the more niche languages.

By learn another language I mean getting to C1 or equivalent. Being able to comfortably spend time in a country that speaks your target language. Having regular, improvised conversations of various depths. Reading literature in that language. Things like that. I really don't think Duolingo can get you there on it's own, but hey, I'm open to being wrong.

I've just have seen many friends keep their Spanish streak for a year or two and I would say they'd still test around the A2 level. I've said it in this thread that that is of course not nothing, but there are much more efficient ways to get to A2 or B1.
