Stories should count for XP!
Just a thought.
Maybe make it like 100xp for a 3 star, 50xp for a 2 star, and 10xp for a 1 star. I think it's a good idea because for people (me included) we can't exactly get to level 25 in a fun way, just have to just repeat thousands of lessons over and over and over and over until we reach 30,000xp.
I have always assumed that if they decide to bring stories out of labs and make it a feature of DuoLingo that they will award XP for the stories just like they do for chatbots in the IOS version of DuoLingo.
I figured that anything I find in the Labs section is temporary and/or experimental so it is in a more limited form so I didn't expect XP from the stories but I definitely would if they become a DuoLingo feature, which I hope they do!
Oh is that how you reach levels, by repetitions? I got knocked down all my levels once because when I was looking at other languages I went back to German and it took me for a new learner; but I quickly when through most of the sections and now I am still at lower level but have 38% fluency at level 9.
