I like Alex's concept of "sponge learning" and reducing "unknown unknowns". I've actually been doing this unconsciously for quite a while.<p>Let's say there is a debate about the best VPS provider on the HN front page. I have no need for a VPS <i>right now</i>, and I sadly don't have the time to read the whole debate.
Instead, I skim the discussion, bookmark it (on pinboard) with appropriate tags, and know it will be there when I do need to choose a web host.<p>This also applies to "unknown unknowns": a month ago, I saw the discussion on CloudFare ( <a href="http://news.ycombinator.com/item?id=2631019" rel="nofollow">http://news.ycombinator.com/item?id=2631019</a> ). I made a mental note that some services might actually help mitigate DDOS attacks, and made a bookmark for later use.<p>I could make an analogy with a database: I don't have enough time / memory to learn and remember everything I read on HN. Instead, I use my brain like an "index", the database being my Pinboard bookmarks. I think it's time to expand to other databases, too: I should try out EverNote or Workflowy to store free-form thoughts and other "non-bookmarkable" stuff.
