How can we make it easier to rediscover great content from our past?

As I was reading this I, at first, didn't get it. I've never been a very active blogger or sharer.

But then it hit me: I realized I've been participating in forums, emailing, chatting, posting status updates, uploading photos to a dozen different services, created at least a dozen different versions of my portfolio, writing thoughts on myspace and friendster, and a hundred other services since my teen years. After a few moments, I realized I've probably easily created 200,000 - 300,000 pieces of data that are, at this point, kind of lost.

It'd be amazing to have a wayback machine for my online life.

The scope of a product like this, though, makes me balk: Cracking the egg of getting all of that data seems pretty daunting.

Edit: Just did a little bit of hard thinking about how many pieces of data I've created and it's probably closer to 100,000. Still a pretty incredible amount of data to create and never revisit.
