Problem 1 is something I'm super into. One place where I think I would use this is in parallel to a web annotation system. Two years ago I had to take a stats course at school and I often found the dry mathematical explanations in the textbook challenging to comprehend. I would go online and search for better answers and often find them. For example a math overflow page or youtube video which makes the problem click in my brain. Now two months go by, and I forget the same theorem. In the back of my mind, I'll remember reading that one mathoverflow page or following a series of links, but now those links are lost in my history.

What I would like to do is annotate the web with data similar to what you are capturing and create 'context chains' as little sidenotes in the margins of the web. Then when I come back to the theorem I'm failing to understand I see a little margin note of the pages I visited when I first read the chapter, and I can immediately regain the context I found in my original study session.
