At the Structure:Data presentation last week Dave Aspery and I discussed some of the common and new integrity issues with big data. One of them was the issue of data tampering and pollution related to marketing campaigns and product placement.
Dave's diaper example was classic. I apologize again to the audience for saying it sounded like a messy clean-up. It would be more fair to say that the damage really depends.
Soon after leaving the presentation I saw this, which nicely illustrates what we were talking about.
