In the whole Instagram TOS kerfuffle, Flickr got a lot of mention. I've had a Pro account with Flickr for years, though my annual subscription payment has felt like a charitable contribution the past few years. For what it's worth, I hope Flickr can start to justify the subscription.
I joked that Flickr had been around so long my photos there had naturally taken on an aged tone. But in all seriousness, I would love to use a service that could digitally simulate the effects of the passage of time on content I had produced, whether it was photos, my writing, music or video. Instead of applying the effect all at once, though, I'd love to see it aged gradually, as if the asset existed in the real world. As I'd revisit my photos or videos, the color tint would change, small scratches might accumulate on the video. The background of my blog might start to yellow a bit, like old parchment.
Since the original is digital, it would always be recoverable, but there would only be one aged copy and it would constantly be evolving. So much of how I mark large periods of time in my life is through the tangible aging artifacts of products that have been with me throughout, and some of that awareness of time's movement is lost in this digital age where everything remains frozen permanently in a pristine state.
