Any Updates on Esperanto Tree 2.0?
Projected dates, etc.?
Hey, I'm working on Tree 2.0. It's progressing very slowly because of some bugs in the Incubator backend, but I think the work could be completed in a couple months. Then Duolingo will A/B test it, meaning that only a small percentage of users would get the new tree at the start and then they will gradually increase the percentage if they see that users learn better with it. Generally it takes several more months before everyone has the new tree.
On the bright side, we're ensuring that the Spanish tree (Esperanto for Spanish speakers) will immediately have most of the improvements of the Tree 2.0.
Do you guys get some data from Duolingo on things like these? I assume they could probably have lots and lots of data on where people get stuck. For example, is there a way to find the "most evil sentence" ... that is, the sentence that has highest percentage of wrong answers? That could be fun info.
