@maegul it's awesome either way -- parallel evoltion, or the idea making it from lemmy to a hashtag posted by Pinetta on a Calckey instance to me seeing it and tagging you on Mastodon.
@pinetta do you happen to remember where you first say the timer "Threadiverse"?
Also it's worth thinking of all of these modes as applied to hashtags and Calckey antennas as well as groups and home/local feeds. Easier said than done I know, but at least conceptually!
