I've been listening for over three months now and I'm very happy with the lesson content and my progress. I think it's great that this site offers not just first-class learning material, but also a constant source of inspiration, which certainly isn't an easy thing to find.
Hoooowever, there are a couple of things I'm really unclear on that I don't believe have been covered in much detail (at least in Beginner S1 & S2), and those would be indefinite pronouns and the word ever/never.
I think a lesson on indefinite pronouns, with a particular focus on 'something' and 'nothing' (for example, can they be used as nouns and adverbs like in English?) would be beneficial to everyone, since I find it hard to survive without these, especially when you consider the frequency of their use in everyday speech.
