Videos on how we use LingQ

I created a couple of videos on how I use LingQ for Czech.

Are these useful?
What other subjects would you like me to cover?
Would you like to see these in languages other than English? Which languages?
Does anyone else want to share how they use LingQ using videos?

I thought they were interesting. I will do mine ASAP.

Thanks Steve. This is confirmation for me that I am on the right track. I did find it interesting that you said that now most of the content you get for Czech is not in the LingQ library. I think I need to get more content outside the LingQ library as well. However, my listening comprehension is uneven at times, depending on the accent, and I can’t really find the kind of content I want with transcripts and audio.

I am looking forward to that video on how you study your vocab.
