What changed
X (Twitter) users can be added as a Watcher source, crawled on a fixed twice-daily cadence. Paid plan only.
Why it matters
The conversations you care about rarely stay on one platform. This puts X posts into the same Dataset as your Reddit and Hacker News records, so one search covers all of them.
How to use it
Add a Watcher and pick X as the source, then give it the account to follow.
