Forums, Blogs, RSS, Newsletters, Twitter, YouTube, Reddit, Hacker News... Sure you often first filter for (or subscribe, or get recommended) content from topics and people that you know you like. But there's still too much stuff to choose from. If you just look at the content from the last day, it is much more manageable to decide what is worth your time.
