What was it?
Livestreaming before it was a button in every app. Acquired, integrated, then starved.
Why it died
Editorial reading
Once live was a tweet feature, the standalone app had no home. Then Twitter live itself withered.
Founder takeaway
Acquiring a verb and burying it in the composer is how you lose the verb.
