What with all the attention on Google right now because of the sweeping and selfish privacy policy changes they just publicized, it’s smart, fun and sometimes a little disturbing to see just what Google’s advertising arm thinks it knows about you. Play along at home – browse to this page from whatever browser(s) you like to use, and compare with what I found.

Frankly, I’m glad that Google has multiple fragmented profiles on me (at least for this usage models of this ad service they sell). If I was to see the exact same data across all apps and devices) I’d be chilled to the bone.
But I’m not naive enough to think they’re not deliberately and inevitably taking us (along for the ride) there. The closer try get to a single, unified, aggregated view of my behaviour and interests, the more they’ll be able to charge their advertisers for every impression and click-through (or whatever new metrics they’re currently stewing up).
Share that revenue stream with me? Then I’m all for the kind of surreptitious gathering that you’re doing. Steal that from me and pretend that “more relevant advertising” is fair compensation (legal: “consideration”)? You know where you can stuff it.
