Sure. I am used to, nay, I _expect_ ads for software tools and music gear given my work and hobbies in my life, as I frequently talk about those things to my friend on FB and IRL all the time. But wiper blades is so off the charts for me, that I was totally surprised to see about 3 ads for them the day after I had a discussion in the car. I don't even go to sites remotely associated with the automotive industry. Not even locality based, as it was a full 4 months out of the real 'wet season' we have later in the year. (NOTE: Not even in our wet season did I see random ads for wiper blades). Having said that, I won't be surprised to see more wiper blade ads now that I have been talking about it on HN - who knows if they have linked up the data from online forums back to FB etc.? The handle I use here I tend to use on nearly all online forums I belong to.
