Zuckerberg is right that the Web is better when everyone shares more. I love that I can discover new music, movies, and articles from Facebook and Twitter. Indeed, following the blizzard of recommendations that pour in from those sites has become the main way that I navigate the media.
That's why I welcome any method that makes it easier for people to share stuff. If you like this article, you should Like this article. And even if you hate this article, you should Like this article (add a comment telling your friends why I'm a moron). But if you're just reading this article—if you have no strong feelings about it either way, and if you suspect that your friends will consider it just another bit of noise in their already noisy world—please, do everyone a favor and don't say anything about it all.
