Ledger

The unverified list

Claims about this subject that circulate widely, that a reader will meet elsewhere stated as fact, and that this publication could not verify to its own standard.

Published 2026-08-06 · Status of facts checked 2026-08-06

A reference work that publishes only what it managed to confirm gives a reader no way to tell a checked claim from an unchecked one. This page is the other half of the Ledger: every claim below was pursued, failed to resolve to a dated primary source, and is therefore not asserted anywhere on this site.

Several of these are the exact sentences a careless account of this subject reaches for first. Some are wrong. Some are probably true and merely unsourceable. The distinction matters, and each entry says which.

Unverified Nothing on this page should be repeated as established fact, including by this publication.

The claims

  1. Who leaked the December 2010 Yahoo “sunset” slide. The internal Yahoo product slide showing Delicious in a sunset column was posted publicly in December 2010. Accounts differ on who posted it first: some credit Eric Marcoullier, others Andy Baio. No original post was located to settle it, so this publication names nobody.
  2. What Yahoo paid for del.icio.us in 2005. Never officially disclosed. Pinboard’s own retrospective describes a range rather than a figure; the flat numbers that circulate have no primary source behind them. The price is written here as undisclosed, which is what it is.
  3. What Pinboard paid for Delicious in 2017. The acquisition announcement states no price. A specific figure circulates widely and could not be traced to any primary source.
  4. Ma.gnolia’s founding year. Given as 2006 in one place and implied to be about 2005 in a 2009 interview with its founder. The two cannot both be right and neither is a primary record, so no founding year is asserted.
  5. Whether Yahoo intended to close Delicious in December 2010. The leaked slide is a document and is described as one. Whether it recorded an intention to shut the service down or to sell it is a different question: Yahoo and the Delicious team publicly denied a shutdown at the time. This publication describes the slide and the response, not a state of mind.
  6. BlinkList’s founding year and closing date. Founding is given as both 2005 and 2006. The only support found for the service running until the end of March 2015 is a single personal blog post written five years afterwards.
  7. CiteULike’s exact closing date. Two dates in late March 2019 circulate. Separately, citeulike.org still returned a homepage with live-looking counters when checked on 2026-08-06 — which is not evidence that anything is running, and was not investigated far enough to say whether it is a frozen copy.
  8. Who acquired Simpy. The April 2010 closure is consistently reported. The acquirer is asserted in one tertiary source and in no contemporaneous report that could be found, so the buyer is recorded here as unconfirmed.
  9. When Digg passed from BuySellAds to its next owner. Repeated in passing in several places, with no dated announcement located. No year is given in the Ledger.
  10. When eSnips stopped. Two different shutdown years circulate and neither could be confirmed. What is established about the company — its founding, and its sale in late 2008 — sits in the Ledger; only the ending is unresolved.
  11. Netvouz’s launch year. A 2008 interview with its founder gives a domain date of 2003 and a public launch in 2005. The year most often repeated elsewhere matches neither and could not be confirmed.
  12. Shadows’ launch and closing dates. That Pluck Corp ran it, and that it was discontinued, are both established. No dated announcement of either end of its life was found.
  13. Clipmarks’ ownership chain. Two acquisitions are reported, around 2009 and around February 2012, with no well-dated primary source for either. The domain’s present redirect is suggestive of where it ended up and is not proof of when.
  14. When StyleFeeder shut down. The January 2010 acquisition is verified. The shutdown date is not.
  15. Founding years for twenty-three names on the 2007 roster. Jots, Listible, 30daytags, RawSugar, clipclip, Searchles, Gabbr, Wirefan, Taggly, Smarking, SiteTagger, IndiaMarks, Complore, Butterfly Project, BuddyMarks, BMAccess, Markaboo, MyBookmarkManager, i89.us, URLex, ListerLister, SyncOne and socialbookmarking.org. Not one could be sourced. Earliest Internet Archive captures exist for several and are not founding dates — they record when a crawler first reached a domain, which can postdate a launch by years or precede a service entirely.
  16. That Google Co-op was “retired”. This one is not merely unverified, it is wrong, and it is the version a reader will meet most often. Programmable Search Engine still exists. What actually happened is narrower: the Custom Search Site Restricted JSON API stopped serving traffic on 2025-01-08, and on 2026-01-20 new engines were capped at fifty domains, the whole-web option was withdrawn for new engines, and existing operators were given until 2027-01-01 to migrate.
  17. Whether the 2007 search engine built at this address still functions. Not tested. This publication makes no claim either way.
  18. Delicious’s user and bookmark counts when Yahoo bought it. Specific figures circulate for both. Neither was traced to a primary source.
  19. Whether folkd.com is still operating. It returned a bot challenge rather than a page to an automated request on 2026-08-06. That is not a check, and “still running” would be an inference from a failure to look.
  20. What the notice now on gnolia.com means. The domain currently serves a seizure notice. By whom, and why, was not established, and it may have nothing to do with the bookmarking service that once used the name. It is recorded here rather than in the Ledger for exactly that reason.

What would settle one

A dated primary document: a company announcement, a contemporaneous report in a publication with an editor, a court or registry filing, a repository commit, or an archived capture that shows the state directly. A second tertiary source repeating the first does not settle anything, and neither does a confident secondary account with no citation.

Corrections that name such a document are welcome and will move the claim out of this list with its date. See Contact.
