@SmartmanApps @ericwickham @rainer you da man!
Bluesky and Mastodon are good starting points given the setup they follow. Once you get into platforms owned by giants, it's a bit more of a pain.
Threads was pretty good. Twitter too, but there's an API cost which is automatically a turn off for many.
Tumblr, Pinterest, and Reddit are straightforward.
LinkedIn is by far the worst one with a public API.
