I started writing notes if I thought it was worth remembering. Too often I'd read the article and then later try to discuss it with someone and forget simple facts. I realized I'm not even learning anything, just temporarily distracting my mind with 'shiny' factoids and stories. Basically the same as looking at imgur all day. I also try to focus what I read and follow only things that relate to my job, projects and 1 or 2 hobby interests.
