Last Known Copy
What the web lost, and how to keep what you save.
In February 2007 someone at this address counted the services where people saved links in public, and listed fifty of them on one page. Of those fifty names, eight still offer somewhere to save a link today and one survives read-only. Eleven are documented as shut down. For the remaining thirty, this publication could not establish what happened.
Last Known Copy is a custody record. Every service, every saved link and every address on this site carries a stated condition and the date that condition was checked. The argument the whole publication makes fits in one sentence: the only thing that ever survives is a copy someone chose to hold.
This is not a tool-roundup site, a nostalgia blog or a productivity system. It ranks nothing, scores nothing and has no opinion about which application is best. It publishes what happened, when, and how that was established.
Two instruments
The Ledger — a dated custody record of the services people saved links into, from the 2007 roster captured at this address to the ones still shipping releases in 2026. Every row carries a status, a confidence grade and the date it was last checked.
The unverified list — the claims about this subject that circulate widely and that this publication could not verify. Published deliberately, because a reference work that only shows its successes is not a reference work.
The 2007 roster, at a glance
Fifty services were named on one page at this address in February 2007. This is where they stand, every row checked on 2026-08-06. The full record, with a source per row, is in the Ledger.
Kept 8 — still offer somewhere to save a link: Digg, Diigo, reddit, Slashdot, Netvouz, BibSonomy, Linkatopia, Fark.
Read-only 1 — del.icio.us, held but closed to new bookmarks since 2017.
Gone 11 — no longer a place to save a link, and the record establishes what became of each.
Unverified 30 — the largest group. Not “shut down”: nobody can now establish what happened. That is the finding, not a gap in the research, and the unverified list says what was tried.

The fifty services one page counted in 2007, and what is left of them
A February 2007 page at this address listed about fifty social bookmarking services in one place. That list is now a census of a vanished layer of the web, and this is what happened to every name on it.

del.icio.us: what is actually left, and what can still be got out
The service that defined social bookmarking passed through five owners in fourteen years. This is its observable state today, not its obituary.

Auditing a link collection for rot: what to check, in what order
Checking whether saved links still work is not one job but four, and the standard advice — use the Wayback Machine — answers only the third of them.
Why this publication is at this address
The domain is named infopirate.org. The name was inherited with the address and is not a description of what is published here — see About, which says so first and at length.
From about 2007 the address ran a social bookmarking community: users submitted links with tags and notes, and voted on them. Those collections are gone. Citations from 2007 and 2008 still point here, which makes this domain an exhibit in its own subject and is the reason the publication took the shape it did.
