Save everything as PDF. Twitter threads, articles or every little piece of information or commentary.
And save videos. Documentaries or short videos.
You just need to right-click and select “Save as PDF”. Or “twitter thread reader” or “stream video downloader” apps.
Don’t leave it to the mercy of the Ministry of Truth. Or search engines or ‘people who are already doing it’.
You will forget, and others will give up. And gone down the memory hole.
