Number of Contributors (especially for the original courses)
A few questions about the number of contributors to both the original courses and the newer incubator courses:
Why has no one been added as a contributor to the original language courses on duolingo? For example, Ker is still listed as the only contributor to Portuguese for English speakers, a course in use by over 1 million people! Can it really be the case that no one has applied to help? Ker is doing great work, but parts of the course still feel like a beta, and I feel strongly this is simply the result of only having one person to manage the workload. Maybe this is why the course still has no speaking component and a relatively poor text-to-speech voice.
What is the thinking behind the number of contributors per course? It seems to vary between two and six (or even just one). Why not 10 or 20 or even 50? I was under the impression that thousands of people had applied. Were their language skills not up to the task? My limited impression of the incubator system is that it seems to be designed to facilitate the collaboration of a larger number of people than are currently assigned to each language.
Perhaps I'm asking these questions prematurely... in a sense all of duolingo is still in a beta state. Will contributor numbers rise sharply in the future?
Some weeks ago one of the contributors of the Hindi course said that the reason was that it's hard to keep a control of the course with a big amount of contributors.
You know, languages can't always be literally translated, and some of the sentences may have many different translations, so they need to have sort of a set of rules indication how an especific phrase have to be translated, and I guess it'd be easy to control with a team of 3 or 4 people, but with a team of 20 people?
Still, I agree with you about the low numbers of contributors for these courses, they should add some more, but the number shouldn't be bigger than 6 x)
I think they are thinking in the sense of 'too many cooks spoil the broth'. Luis said more than once, that they personally vet the moderators, to evade low quality courses.
I'm not sure why they is still one contributor for many courses though, maybe they have their hands with vetting contributors to new courses.
