Habs fan here, let's see how this thing work!

Ah, then unless I go and search all instances for, say, /c/hockey, these will have different posts. This is a shame.

But thank you for taking the time to answer my questions :)

So, if I go to lemmy.ca/c/memes do I see the same content as on lemmy.ml/c/memes ? That's the major issue I see but maybe I am mistaken and both "points" to the same content ?

I would love to know too. Maybe a link to a Lemmy how-to ? I have a true fear of missing out I think. For example, if I follow /c/hockey on lemmy.ca, do I also get the posts from other instances ? Someone help us ! :)
