The current holdups are that .com does yet support DNSSEC (it should happen early next year), and that people are still figuring out what form the DNS records should have. At this point, it's likely to be a new (binary) RR type which doesn't have an RRTYPE code assigned yet. I just need to change Chrome to reflect this.
Very little of your site transmits sensitive information. Its actually a little disconcerting to be forced to use HTTPS to see a simple blog post.
