Tumblr sat in the menu with nothing behind it: the page searched Tumblr live and kept nothing. It now reads our own store, which grows every two hours and re-reads saved posts so their note counts move, and there is a public archive of the most-noted posts by year.
For a year the Tumblr page was a search box that asked Tumblr's API on every visit and forgot the answer. No history, no trends, nothing to sort. It is a real network now.
- A sweep every two hours reads the tags that matter on Tumblr (Tumblr has its own vocabulary, so the list was learned from Tumblr, not copied from TikTok) and keeps digging into each tag's history, so the store holds more than a single pass could see.
- Saved posts are re-read so their note count moves. Tumblr reports one number per post, notes, and a post that leaves a tag's recent feed is never shown again by the API, so without re-reading it would freeze at first sight. The second indicator on the card, growth, is ours: the gap between two of our own readings.
- The Tumblr page in the app sorts by hot, most viral and newest, filters by tag and by note floor, and pages properly. Searching a tag we have little of asks Tumblr for more and keeps it.
- Public Tumblr archive, the most-noted posts of each year, which Tumblr itself does not let you browse.
Tumblr posts carry one metric, notes, which is likes, reblogs and replies already summed. There are no separate comment or share columns because Tumblr does not publish them, and we will not invent them.
