Yeah, I know, I definitely don't think it should make the UX more complicated, introduce yet another "concept", that's the biggest worry. Maybe it would be worth looking into what are the different types of situations that people face with context and maybe some types could be handled by different features.

There were definitely times where I found the content of the context comment useful. I scanned through the podcast timeline, or just read through the summarized point of the article (and decided not to actually read the article).
On the other hand there were definitely times where it felt spammy and I wished I wouldn't need to scroll through it...
