Questions
Because people still search for them. Someone who bookmarked a tool in 2011 and comes back to a parked domain has a real question — what does this now? — and deleting the entry deletes the answer. Keeping the record with a named successor turns a dead end into a redirect.
Roughly half. The viral lists of the late 2000s and early 2010s recommended a few hundred sites; social bookmarking, Flash-era media hosts and standalone video communities were hit hardest, while single-purpose utilities and reference archives survived best. That pattern is why the Atlas records status as data rather than assuming a link works forever.
By the job, not the branding. The successor is whatever currently does the thing the retired site was listed for, even when it looks nothing like the original — a social bookmarking service is usually replaced by a read-later queue rather than by another social bookmarking service, because that is where the behaviour went.
Still standing
The other half of the story — entries from the original lists that are still live, still free, and still the best answer.
