@danieldekay no the same - I have hundreds of different followers on each network, although all could follow on either one. I post manually to Hubzilla, but my Friendica site auto-posts from my blog RSS feed.
Both networks are profile -only posts, so no separation into topics like Google+ had. I loved posting into topics as that gave some focus for followers. Actually think Reddit has that inside channels, but I left Reddit for Lemmy.
