Summary
Karl Voit argues that writing valuable knowledge into closed, centralized services (Reddit, HN, Facebook) is equivalent to donating books to a library about to burn down. These platforms provide no backup/export mechanisms, block Wayback Machine crawling, and will eventually shut down — taking all contributed knowledge with them. The alternative is publishing on your own domain with open standards.
Karl Voit 認為，將有價值的知識寫入 Reddit、Facebook 等封閉中心化服務，就等於將書籍捐給一座即將被火焚的圖書館。這些平台不提供備份/導出機制，阻止 Wayback Machine 爬取，最終關閉時所有貢獻的知識也會消失。
Key Points
- All centralized platforms will eventually shut down — popularity is no guarantee of longevity (Google killed 300+ services)
- Reddit blocks Wayback Machine archiving; no open API; no user data portability
- 2024 updates: Reddit sold user data for $60M/year; locked search engines except Google; author left Reddit for good
- Alternative: personal blog on your own domain — Internet Archive can backup open web pages
- IndieWeb movement as the philosophical alternative to platform-centric content
Insights
The “Library of Alexandria” metaphor is effective but the more concrete proof is the list of dead Google services (~300 entries by end of 2024). This isn’t a niche concern — valuable developer knowledge locked in Reddit threads (tutorials, debugging solutions, architecture discussions) is routinely lost when threads go 404 or subreddits are archived. The argument applies equally to knowledge bases in closed corporate tools (Confluence without export, Notion with lock-in, etc.).

Raw Excerpt
TL;DR: all of the content of closed, centralized services will be lost in the long run. Choose the platform you contribute to wisely now instead of learning through more large data loss events later-on.
