Lol, that’s what happens to me also. Then I want to go back and recap from the source to see if there were any updates or new discoveries at the topic source but it has been so long the link is dead and now gone. When this happens it blows my whole argument because I can’t link to the source and prove it anymore. “I swear! it was there!”.
Yeah, the rise of the paywalls and the permanent problems of lost links and/or vanishing link syndrome has led to my habit of saving pages or their text and links.
