Corrections vs Beta
Once the language is out of the beta phase, does this mean that reporting bugs and incorrect phrasing, idioms, etc. to Duolingo will be ignored? Correct me if I'm wrong, but doesn't beta just refer to the test program which once finalized and launched is the best that it can be? Does it mean that minor corrections and adjustments can no longer be done without updating the entire program?
I wouldn't think so. The other (non-beta) languages still allow you to submit corrections. Beta just means that bugs are to be expected and that perhaps all the features aren't there. Non-beta doesn't mean it's bug free or even complete. It just means, typically, that it's stable enough and feature-rich enough to be used by people with a lower tolerance for bugs. I suspect, as they move out of beta, they may rearrange some of the lessons based on the feedback or add speech input questions, which seem to be missing from Italian (Beta) at least.
