Some further info having to do with a post I put up yesterday on tools to keep advertisers from getting information on what products and services you google. This was part of a conversation on Facebook:
"Not one hour after I buy something from anywhere on my iPad, ads from that place show up on my Facebook on my iPod."
Most commenters had the same experience and theirs did not just mirror ipad, but also computer purchases. This comment in particular caught my eye:
"Mom and I will discuss something and not an hour later are we seeing similar things we were discussing on our Pinterest feed."
Some time back I posted about how I believed Siri heard and remembered everything we talk about and sends that info to marketers and this just reinforces my belief. At the time I turned Siri off and things really have been better, at least as far as her overhearing conversations about things we plan to buy. The same thing seemed to happen around the Amazon Echo. I only have the Echo turned on when we want to use it.
