What is the difference between rus.stackexchange.com and russian.stackexchange.com?
From the description of the russian.stackexchange website,
Russian Language Stack Exchange is a question and answer site for students, teachers, and linguists wanting to discuss the finer points of the Russian language. It's 100% free, no registration required.
From the desription of the rus.stackexchange website,
Русский язык — сайт вопросов и ответов для лингвистов, этимологов, и энтузиастов русского языка. Совершенно бесплатный и без регистрации.
So, how can I decide whether I'm a "student, teacher, and linguist" or a "linguist, etymologist, and enthusiast"? The only major difference I am noticing is that russian is generally in English, whereas rus is generaly in russian.
