Reciprocal data
A recent TechCrunch article sugggests one can import their Facebook contact personal email addresses using Yahoo.
After a couple unsuccessful attempts, it worked. But I especially like the article for pointing out the lack of reciprocal-nes inherent in these service models. Wouldn't it be fair, since they're collecting it, if we could access all that data that they're collecting anyway? You can bulk download all your Facebook content in one big zip (though this wasn't available to me last time I checked), but why not be able to see who's accessing your pages, and where our likes are being published (Microsoft search results, among other places).
Let's carry this a little further. If you have an Internet service provider or use a mobile handset, they have access to massive amounts of information about you. All the web sites you visit, all that unencrypted email, even where you are. As they built their own capture systems, why not provide access to this data?
People often talk about "smart fridges" that know what's in them, imagining people scanning oranges as they 'input' them, but why not just access your latest grocery receipt electronically, if not online through a points program? (I asked about this at the Metro grocery chain, it just led to total confusion at such a concept).
This is all part of embracing invasion of privacy to mutual advantage, which has many drawbacks, but it seems inevitable.
