I also would reccommend googling stuff. You have an area of interest just Google it or something related to it. For stuff like this it's too bad Google removed the "I feel lucky" button (or is it still there but hidden somewhere?). Another great way to fond a starting point is to go to wikipedia and clicking the random article button and just start reading. You'll be surprised at what things you actually might find interesting.
