Look, I'm one of those people that doesn't mind relevant, unobtrusive advertising. Yea, my mind is trained to just ignore and not even register online advertising, but sometimes when I'm looking for something or researching new products, I go down the advertiser link holes.
But right now with the third party tracking, I get *worse* advertisements than I used to. It's ridiculous. Just yesterday I went to Levenger.com and bought some refills for a notebook. Literally, over 90% of the ads that I see now are Levenger or Levenger's competitor's ads. There doesn't need to be any Levenger advertising, I just bought from them! I can actually do a search for computer motherboards right now and ads for Levenger paper come up.
If I click a link and look at a simple product on Amazon, that product's ads track me and stay by my side no matter where I am until I look at some other item. Right now, online ads are waaaay too far on the tracking side; I hardly ever get contextual ads any more. It's all about getting me to buy whatever was the last page with a buy button on it that I navigated to, even if I already bought it! Talk about dumb.
So, yea, I think that the state of internet advertising might actually get better without these trackers. They might have to actually detect what I'm interested in and serve up relevant ads, rather than plastering every page with a freakin' ad for paper that I already bought. Kudos Mozilla. I might just switch back from Chrome...
