In addition to some of the great sites already listed, I frequently check these:
http://www.grahamhancock.com/
http://www.surfingtheapocalypse.com/
http://www.dailygrail.com/
also just for food for thought & pure entertainment:

I have to admit that although I do peek at Rense occasionally, I find him too "in your face" (i.e Fox newish) for my personal taste.
Happy surfing all
