From one recruit to one thunder: install Blowhorn on as many computers as you like, they fall in as one unit, and one order goes out to every channel at once.
Your changelog already says what shipped. Here is how to have an assistant turn it into release posts for the networks your buyers read, queue them for a good hour, and still keep the decision to send in your own hands.
Every write through the Blowhorn MCP server is a dry run until you confirm. What a rehearsal shows, what to check before you say go, why an agent can never approve its own content, and what approval mode and secrets handling add.
A tagged release deserves notes written for each place your contributors read: Hacker News, GitHub, Reddit, Slack and Bluesky. Why channel-native wording beats pasting one post everywhere, and how to preview each before it goes out.
