People were adding their own take, which is how a launch gets argued about and carried into audiences the account does not have. Bookmarks: 892. Reposts: 210.

It starts “Today, we’re launching support for Chrome extensions in the ChatGPT desktop app”, a first-person opening that the founder-account launches in the directory use most. It carries a 15-second video against a directory median of 65 seconds. Videos under 30 seconds have a median of 850K views in the directory.

The copy runs 45 words, about the usual length for a launch post here, where the median is 41. There is a link in the body, which costs a post some reach and buys it a place to send people.

It went out on a Friday. Launches posted on a Friday have a median of 880K views in the directory, which makes it the strongest day.

Attributing signups to a launch covers this: a save rate this high is the number to follow into the product. For the next one, read giving people something to reply to: the conversation is what carried this one.
