I have subscript the HackerNews RSS Feed. Using Thunderbird as my RSS client it bothers me to see multiple copies of the same post in my inbox every time the title a post is changed. Adding the <guid> tag containing the post id can help the RSS client to
distinguish posts.
The Seldon Plan:
1. Start a foundation.
2. Locate it at the outer rimes of the civilised galaxy.
3. Implement a technocratic cult governed by a dynasty of priests.
4. Engage in psychohistorical research for envisioning future risks.
