Post to Reddit and Bluesky

Queue posts for Reddit and Bluesky from content rows, then publish them with blowhorn post.

Reddit: post to a subreddit

Set Title, put the text in Message Text, and put the subreddit in Destination as r/<sub>:

blowhorn content upsert --payload '{"Platform":"reddit","Profile":"kate","Title":"Meshery v0.9 is out","Message Text":"What is new in this release...","Destination":"r/meshery","Approved?":"yes"}'
blowhorn post --platform reddit --profile kate --dry-run
blowhorn post --platform reddit --profile kate

A title longer than 300 characters is cut short with a warning. A row with no subreddit in Destination or Amplify is skipped with an error naming the row.

A comment on a thread is a Comment on row, and an upvote is an Amplify row; both are on their own pages.

Bluesky: post and thread

Put the text in Message Text. Past 300 characters the post splits into a thread at word boundaries:

blowhorn content upsert --payload '{"Platform":"bluesky","Profile":"kate","Message Text":"Meshery v0.9 is out...","Approved?":"yes"}'
blowhorn post --platform bluesky --profile kate --dry-run
blowhorn post --platform bluesky --profile kate

A thread that stops part-way is recorded with what landed and never retried: re-running it would post the landed part twice. Read the run's !!! line before you touch that row again.

A row with Image URL attaches that file. A comment on a post is a Comment on row, on its own page.

Bluesky: repost

Put the post's Bluesky URL in Amplify and leave Message Text empty:

blowhorn content upsert --payload '{"Platform":"bluesky","Profile":"kate","Amplify":"https://bsky.app/profile/meshery.bsky.social/post/abc","Approved?":"yes"}'

Unlike LinkedIn reposts, a Bluesky repost is not guarded against a second run: once the row is done, leave Date Promoted alone.
