Killed 2017 (Pinboard buyout)

Delicious

Founded 2003 · Peak: 5.3 million

Why Delicious mattered

The original social bookmarking site. 5.3 million users. Yahoo bought it in 2005, sold it to AVOS in 2011, then Science Inc, then Pinboard in 2017 — Pinboard's sole purpose for the acquisition was to kill it.

Why this matters in 2026

Big Tech killed every great community-driven internet tool between 2008 and 2024. Delicious was one of them. SENTINEL is the unified replacement — 7 dead products reborn as one AI-powered platform on owned infrastructure, free forever for personal use, no tracking, no ads.

All AI runs on local Llama and Qwen models — no OpenAI bills, your data never leaves our server. Stripe-powered subscriptions for paid tiers, free forever for the basics.
