I think this is a great article that covers quite a lot of topics. It reminded me that we're already aware in real life of the importance of being able to 'expunge' or seal certain forms of records (e.g in law or financial judgements, I believe), yet we've gotten away without such things for the data that ends up online about us. This will matter even more as devices etc become connected to the Internet and it's worth having such debates now.

It's also worth remembering that the entities that index, store, and present this data to us have their own motives for doing so. We should not be so quick to assign some kind of hallowed status upon them.
