HW/FW security researcher & Demoscene elder.
I started having arguments online back on Fidonet and Usenet. I’m too tired to care now.
Even though apps interconnect it’s a good idea to use the best client for the service. But, sure - I can start following “@3dmvr@lemm.ee” from my Mastodon account. It’s also possible to subscribe to a Lemmy group from Mastodon, and reply to it.
But the best user experience is had by creating a Lemmy/Mbin account on such a server and interacting from there - like I am with my fedia.io account here now.
Yes, I know :) (I run a family instance with FediFetcher and relays as well)
Large instances are usually well covered enough. I don’t know if Lemmy/Mbin pull sll posts for a thread you visit but Mastodon has plans to do so in the future to alleviate this issue.
