It'd be pretty nice if the last blog post was more recent than 3 years. It's also really nice to know that curvedns-0.87 has been downloaded 1050 times... but i have no idea when it was actually released. No sign of a changelog... No public repository? No mailing list?
All of these crypto projects (Nacl, CurveDNS) would benefit from moving to Github. Nobody's going to use a seemingly stagnant project. That's ultimately the problem with most of djbs best work, and a lot of other good work, I think. He does world class research and reference implementation, but it doesn't feel like there's an open source community rallying around it.
We need more Linus' in the crypto world.
I get about 1-2% of my requests via DNSCurve, almost entirely from OpenDNS, which started supporting it years ago: http://blog.opendns.com/2010/02/23/opendns-dnscurve/
The problem is mainly in the tooling - there aren't good query and diagnostic tools out there for DNSCurve, beyond fairly complicated CLI incantations.
