Scrapbox look-back function

2021-08-06 One click generates the following page Intended use.

• Click on the menu whenever you feel like it
• View generated pages
  • Follow the link if you want to follow it.
    • If you want to rewrite the link, rewrite it.
    • I won't rewrite it, but if you want to comment on it, you can write a comment on this look back page like "I used to write this, but..."
      • They may look at multiple links and find relationships.
      • If you want to write it and then title it further and make it a stand-alone page, do so.
  • If you see something and don't feel like taking action, delete link.
    • Maybe this is important
    • If you don't do this, you'll have more meaningless links and your Scrapbox will become a garbage dump.
  • I think you should remove the links, even the ones that rewrite the page you linked to.
    • Because there's not much point in information that says, "I looked back at this day in retrospect."
  • Ideally, this look-back page should be used as a temporary home for the information generated by the look-back, and the page should eventually scatter and disappear.
    • If you can't find a good place to stay, you have no choice but to stay here, like Nodes of Thought.

Comparison with previous version [ScrapboxSRS

• I think we used to give out too many links.
  • It would be a burden to see it all.
  • There was an unnecessarily large amount of other information.
  • I hadn't seen them in three years, and I was like, "No, there's too many of them."
• Interpretation of the meaning of the score is difficult and not good.
  • So I made it "100 days ago", "1 year ago", and "n years ago".
    • n years ago" is anything other than one year ago that is a near multiple of one year.
• I made each section three.
  • I think about 9 3x3's is about right. This is the intention.

I used it. - Reflections on "2021-08-05 Reflection"

• I changed the external project link notation so that the link does not appear in the related pages list even if the link remains.
