Feel free to clarify what kinds of information you are searching for. The answers might vary a lot depending on what you are looking for.
For current events, The Economist is great, IMHO. Other good publications: The New York Times, The Guardian, BBC. Maybe The Washington Post.
Quora has some good info but the quality probably varies a lot.
BTW, did you know Hacker News has a search function? Really good.
HTH.
