Real engagement, not passive. Even discussions like these aren't always memorable. It's like driving the same route to and from the office for years, at some point you start arriving home or at the office with little recollection of what happened in between. You weren't asleep, but you made few new memories if nothing out of the ordinary happened (days I remember: Seeing a red truck on its side off the road, the days deer or antelope cross the path, the time a cow decided to turn up on the road, etc.). So what are you doing on the internet? Just reading? Is it creating new memories, new connections? Sometimes, but how frequently? What if you try to actively engage with the material, make summaries, try out the ideas in a small project, anything.
