@manton Yeah, the domain thing is probably going to be a much bigger challenge than keeping data and servers alive. What happens if your TLD ceases to exist? .oz and .su are no longer with us, for example. And your blog's content might not break your registrar's terms of service today, but what about tomorrow? Or fifty years from now? And what about future laws? Your blog might be legal today, but not in a decade.
Will Automattic register a new domain for you if the old one is lost? Will they rewrite your blog's content to comply with future laws? It's an interesting challenge!
