Ha! I was just thinking this exact thing last night. There's lots of examples, but the one I experienced was searching for info about a product I am thinking about buying. Nothing but stores and marketing on the first couple pages. Tacking on review to the search brought up nothing but marketing copy and fake blogs from the various retailers. Tacked Reddit onto it and finally found people's actual thoughts and experiences. It's a damn shame and I suspect only a matter of time before Reddit is overwhelmed as well.
