The "but" is that I will almost certainly outlive this service. I don't remember the name, but there was something similar, though a bit more built up and polished, a few years back. Seems like a good idea, so I set it up. A year or two later, it was gone. Thankfully, I'm not.
I love the idea of something like this - even better if it included some digital housekeeping, deleting what I'd rather delete, and sending what I'd like to share - but I think I'll have to build and maintain it for myself if I want it to last.
