I feel like even their main products are shoddy as well. How can they recommend good, relevant ads if they can't even recommend good news articles, music, or videos? If I do any search in Google on a topic, even if it's just to get a tiny bit of info about that topic, Google decides I'm interested in it and will make recommendations based on that one, single search. Or sometimes I'll buy a product and start seeing ads for similar products later. That's not good targeting IMO.
