Today in useless marketing-driven product innovations, we have Huggies TweetPee, a little sensor dreamed up by Ogilvy Brazil that affixes to your baby’s diaper, syncs with an app and tweets at you whenever it detects pee (in the form of a higher humidity level). This will work great for people whose parenting consists of the occasional diaper change in between marathon Twitter sessions. Evidently (it’s somewhat hard to tell from the case-study video) the app also keeps track of the number of diapers you go through, and alerts you when you’re running low. That may be the whole idea here—getting you to blow through diapers quicker by prompting you to change them every time the kid pees a little bit. In that regard, TweetPoop might be more useful than TweetPee—getting the kid out of a poopy diaper faster has its benefits. (You could call it “DM Your BM.”) The problem, of course, is you don’t need a fancy sensor to detect that.
