There used to be a great bot, but it died and never came back. Would love to find a working one! (Am getting a bit tired of reading HN headlines. ^_^)
EDIT: if it helps, source code for the dead bot is here: https://git.fuwafuwa.moe/albino/lobstertoot
Alternatively, a currently active rss-to-mastodon bot : Feed2toot
Not that I know of, but I’m happy to help if someone needs help setting one up. And I’ve mentioned it in chat, but I’d accept a PR adding Mastodon support similar to the existing Twitter support: a setting for one’s username, a list (if that’s a Mastodon thing), an official bot that @mentions usernames when available.
Luckily the dead bot does have a git repo, so maybe some hero could try forking that and setting it up? I’d do it myself, but am already overloaded with work.
They are but not in the way the bot would need to do.
If the atom feeds here were WebSub-enabled then they could be followed directly without a bot.
(Mastodon might also require something else, like a Webfinger endpoint, not too hard to add. They don’t exactly believe in following the specs… :P)
