Follow any tool, company or technology. Every Friday, Last30 sends one letter with what changed this week — read from Reddit, Hacker News, GitHub, YouTube, arXiv and the web, clustered into stories, every claim with its source.
A company, a product, a technology, a person. One line is enough — no keywords, no boolean queries.
From 20+ platforms — Reddit, Hacker News, GitHub, YouTube, X, Bluesky, Threads, TikTok, Instagram, LinkedIn, arXiv, Techmeme, Digg and the web — clustered into stories rather than listed.
One letter across all your topics: what mattered, what is just starting, what others are reading. Each week is diffed against what you have already seen. A quiet week says so, in one line.

◐ partly. Google Alerts sends only new links and offers a daily or weekly digest, but nothing groups stories or says when a week was quiet. AI search (Perplexity) cites Reddit heavily and can run a search on a schedule, but each answer starts from zero. Checked September 2026.
The web, Reddit, Hacker News, GitHub, YouTube, X, Bluesky, Threads, TikTok, Instagram, LinkedIn, Pinterest, arXiv, Techmeme, Digg, StockTwits, Trustpilot, Amazon reviews and the Meta Ad Library. Which ones run depends on the topic: a coding tool is read differently from a game, a drug or a company. A typical run reads 100–150 posts, threads, articles, papers and videos.
No editor, no agenda, no sponsor. Every claim links to its source.
