The author says this is a very early state of a salmon-plugin for WordPress. There are still some bugs and problems… Please let me know if you found some.
As updates and content flow in real time around the Web, conversations around the content are becoming increasingly fragmented into individual silos. Salmon aims to define a standard protocol for comments and annotations to swim upstream to original update sources and spawn more commentary in a virtuous cycle. It’s open, decentralized, abuse resistant, and user centric.
