I am so interested in this, but there are so many things I don't understand. I wonder.... is there a service (Maybe a chrome extension) that lets you ask questions on the page you are in? For example, I want to highlight: `btrfs-progs` and ask... "What is a quick summary about this package? `ship a new enough version of util-linux` and ask.... "What features in the new util-linux allows this to work?" Then maybe someone who also visits this page with more knowledge can answer my questions. This tool would augment my learning 10x and I would be a paying customer. Does something like this exist?
