It got even better a few months ago when they started offering transcripts of the videos. Those, however, weren’t great for English Language Learners, since you can’t scroll down a transcript when you’re watching a video.
I just discovered today, though, that they appear to now have subtitles for ALL their videos. Just click on “subtitles” and you see them.
I’m not sure when they started offering this service, but it will be a huge help for English Language Learners. As far as I can tell — and I hope someone will correct me if I’m wrong — it’s the only new website that offers that feature for all its videos.
