But see, they're still putting you in a box! Now you will be more likely to encounter stereo mixers than other types of products. Sure, it's obvious and on a small scale, but when every website is doing it, what's the cumulative affect?

Choice is good. I've certainly groaned at my share of ads on traditional television, and so I can understand why someone might find targeted ads preferable. I just don't share that desire!

Amazon in particular irks me because they don't give you a choice, no matter how deep you dig into settings! You can turn off browsing history, but it's stored in a cookie per-device and also seems to randomly come back on sometimes. Even then, they'll still use your purchase history for recommendations. I used to manually go through and mark everything I bought as a gift, and this worked for a while—but then Amazon apparently decided I'd given to many gifts and started ignoring the signal.
