Take this post, for instance:
https://fedia.io/m/lemmyworld@lemmy.world/t/6403/Does-lemmy-world-allow-criticism-of-the-CCP
The user and magazine are both from Lemmy.world, but next to the title it says (fedia.io). What does that site in the parentheses mean?
There’s a notifications section (in user settings) which has options for “response to my comments”. They were all off for me by default. I do get notifications but I got a couple this morning for things I’d already clocked had been replied to yesterday, so they are seriously delayed atm.
