This is @Dave’s comment from the daily kōrero:
Do we need guidelines about using it? Like sure you can subscribe, but what about cross posting to !newzealand?
Cross posts ok? Guidelines on not cross posting questions just links (articles etc) because the questions don’t come with the answers? Any thoughts?
Personally, I think it’s fine for people to cross-post stuff they think is relevant to the communities here. I’d prefer it over links to Reddit, because it lets people engage with the content here. I doubt posts in !newzealand@lemmit.online will get nearly as much attention as the ones on lemmy.nz. The Lemmit bot makes it pretty obvious that it’s taken from Reddit. I think one guideline would be not to remove the bot’s text from the post, nor the “cross-posted from” text that’s generated when it’s cross-posted here.
As for question posts, it would be a weird thing to cross-post. I guess if someone wanted to give credit to the OP on Reddit. I can’t see that happening too often, unless it’s a pretty broad question that generates discussion - in which case, it doesn’t seem to matter to me if there’s a separate discussion going on here.
