The internet is, in my opinion, the most important wonder in the game (besides perhaps the Pyramids). Many a game has been salvaged by being the first to get it; I have on occasion received 10 or more techs from it. Granted some are military tradition and divine right and such, but often I also get flight, fascism, sometimes communism... frankly, it's extremely powerful for any game you are not completely dominating at the end.
