To be fair, the most over-engineered blog I know of is anything hosted on top of this: http://arxiv.org/abs/1312.7152 ;)
"This paper proposes a new microblogging architecture based on peer-to-peer networks overlays. The proposed platform is comprised of three mostly independent overlay networks. The first provides distributed user registration and authentication and is based on the Bitcoin protocol. The second one is a Distributed Hash Table (DHT) overlay network providing key/value storage for user resources and tracker location for the third network. The last network is a collection of possibly disjoint “swarms” of followers, based on the Bittorrent protocol,..."
(and I am sure someone will come up with an example of a blogging platform that starts at the level of specialized mesh networking hardware or something like that...)
This isn't quite as crazy, but in the spirit of overengineered blogs, this guy tried to make every single element of his blog optimized by automatic A/B testing: http://www.metamorphosite.com/about
