blu.cx (elmstatic). Generates 14 post pages, section indexes, tag pages,
and a home page with snippets grid from markdown content.

+I started out by working at Chick-fil-A in the kitchen, then as a programmer for corporate.
+
+Most of my work since then has been in Bitcoin: one of the most fascinating
+technological developments of our time and the most promising of the emergent currencies.
+
+I work at Voltage in pursuit of that curiosity, working on streamlining
+payments via the Lightning Network.
+
+I also work on numerous Bitcoin side projects, primarily Payjoin: a novel method
+that makes transactions more scalable, cheap, private, efficient, and fun.
+
+It is believed that if we can get even a small percentage of the total number of Bitcoin transactions
+to use Payjoin, we can break the most common metric used to spy on people today: The Common-input Ownership Heuristic.
