Along those lines, I've started a new subreddit exclusively for posts that help you learn important things. http://www.reddit.com/r/learnit/ http://www.reddit.com/r/learnit/ I've found the most useful time I spend online is reading good introductions to concepts/subjects I wish I knew more about, and I want to do more of it. Hence the subreddit.
