Rationalist sites worth archiving?

One of my long-standing interests is in writing content that will age gracefully, but as a child of the Internet, I am addicted to linking and linkrot is profoundly threatening to me, so another interest of mine is in archiving URLs; my current methodology is a combination of archiving my browsing in public archives like Internet Archive and locally, and proactively archiving entire sites. Anyway, sites I have previously archived in part or in total include:

  1. LessWrong (I may’ve caused some downtime here, sorry about that)

  2. OvercomingBias

  3. SL4

  4. Chronopause.com

  5. Yudkowsky.net (in progress)

  6. Singinst.org

  7. PredictionBook.com (for obvious reasons)

  8. LongBets.org & LongNow.org

  9. Intrade.com

  10. Commonsenseatheism.com

  11. finney.org

  12. nickbostrom.com

  13. unenumerated.blogspot.com & http://​​szabo.best.vwh.net/​​

  14. weidai.com

  15. mattmahoney.net

  16. aibeliefs.blogspot.com

Having recently added WikiWix to my archival bot, I was thinking of re-running various sites, and I’d like to know—what other LW-related websites are there that people would like to be able to access somewhere in 30 or 40 years?

(This is an important long-term issue, and I don’t want to miss any important sites, so I am posting this as an Article rather than the usual Discussion. I already regret not archiving Robert Bradbury’s full personal website—having only his Matrioshka Brains article—and do not wish to repeat the mistake.)
