The Jellyfin blog achieves one important criteria: when you click the logo at the top it takes you to the actual homepage, rather than a blog homepage. So if you want content on what Jellyfin is it’s only one click away.
It's not really a plex clone inasmuch as it's a truly self-hosted alternative, given that plex uses centralized auth (aka you're possibly back to VLC if your internet is out).
I've used Jellyfin for years now, hasn't really skipped a beat aside from dumping the entire library DB when it started without the library storage spun up, and even that was just a rescan overnight and everything was back and happy.
