Social signals from open networks
Trending tags and links, ticker and crypto social volume with tone, hot discussions and GitHub star velocity from Bluesky, Mastodon, Nostr, Lemmy, Hacker News, Lobsters and GitHub.
Counts and spikes collated from open social networks that no single API merges: hashtags and shared links from the Bluesky firehose, Nostr relays and twelve Mastodon instances; ticker and crypto mentions against a 30-day baseline with lexicon tone; Hacker News, Lobsters and Lemmy front pages in one list; fediverse size from FediDB; GitHub repos gaining stars. Aggregates only: no post text, handles or user profiles. X, Reddit, Threads, TikTok and YouTube are not sources.
