Timehop is a mobile app that scrapes your various social networks to provide daily snapshots of what you were tweeting, updating, and publishing around the web one, three, five, and maybe even nine years ago. One gratifying moment I look forward to is Timehop’s scraping of my Flickr.com account, the recently revamped photo site, and the showcasing of my underexposed, contrast rich, and horribly composed experimental moments of my youth. Usually I feel a tremendous pang in my gut that makes me visually grimace (although to myself), but then recedes. Shortly thereafter, I remember that these images came from many years of exploration and experimentation, and delight sets in. Emotions from distant years surface and, instantly, nostalgia.
