As the Kindle Deletion Disaster continues, I'm seeing a lot of analyses of what this means. Yes, there's what it does to Amazon, there's the political repercussions (what's to stop a government from manipulating omni-delete features), and there's more to come. I'd like to add one thing the Kindle Deletion Disaster does to writing: it affects trust.
Trust is a very important thing in the world of media, as we geeks and fans know. A company can loose trust with a lousy game, by cracking down on fansites, etc. But the Kindle and similar technologies give companies – and creators – a chance to completely destroy trust in their work by doing boneheaded things.
