Huginn is a system for building agents that perform automated tasks for you online. They can read the web, watch for events, and take actions on your behalf. Huginn’s Agents create and consume events, propagating them along a directed event flow graph. Think of it as Yahoo! Pipes plus IFTTT on your own server. You always know who has your data. You do.
This is intriguing. Written in Ruby, Huginn allows you to create agents that will scour the Internet collecting information you are looking for, act on the information, and report back to you. I think this would be useful for someone who likes to keep track of lots of stuff.
