Yeah, but people move on too. Do you expect every single person who ever contributed to repost their content when a migration happens? Of course not. It's just not realistic. But actual info gets lost. Old game faqs vanish. Answers to niche questions poof out of existence. Yes, the world isn't over and things will move on. But actual, tangible value was lost with the death of reddit. A large portion of the internets "How To" guide just went up in flames. And a lot of that won't ever get rebuilt. Many of us who have been around long enough have also seen that dark side to these things.
It's a shame, is all. But time keeps moving and so will we.
