Ask HN: Does cross-posting to Medium still help, or does it just dilute SEO now?

I’m building a small tool that syncs WordPress posts to Medium using canonical URLs to preserve SEO. Before I go further, I’d love perspectives from people who actively publish:

• Is Medium still worth distributing to in 2025? • Have canonical links actually protected your SEO in practice? • Do you cross-post manually, with scripts, or not at all?

I’m trying to avoid building something people used to want but no longer do.
