I really like the stories but do you all think that they should have different levels of stories? like beginner, intermediate, and expert. I also think they should make different languages for it to. what do you all think?
See this comment from vivisaurus, who stated that they're testing the project on a small scale right now to see how effective it is before they expand it onto other platforms, languages, etc. This is how the Labs section will work; users are given the privilege to get a glimpse of some of the projects that the staff is working on currently.
I like your first idea; Great for Spanish beginners like me! Since the only language I am seriously learning is Spanish, I am quite fine with only Spanish and Portuguese, but I know a lot of other users who don't study either are very bothered and disappointed about that. Vivisaurus, an Admin, explained why there are just those two languages: They were the only ones they had access to. I hope in the future there are more languages, but to be honest, vivisaurus made it sound like there wasn't going to be for a long, long, long, time, if ever. I hope we'll get them one day, because I am definitely going to do more duolingo trees in the future, and not just Portuguese.
