Would you be able to share an example? (Short description or screenshot is fine)
We might be able to clarify or add it to the guides in the future
The question was "What type of stuff are you buying off Aliexpress?"
I started responding with "toys, cleaning supplies, phone cases, etc." And then I noticed I was responding to a post on ** Aliexpress@programming.dev**
So I felt like my response wouldn't be as helpful or would be off-topic because I was responding on the programming.dev instance.
Right? That makes sense right? LOL
There's actually no harm in commenting on communities from another instance!
Often there will be one large community for each topic, on some random instance, rather than individual communities on every instance. The diagrams on this doc might help to see how it works: https://fedecan.ca/en/guide/lemmy/for-users/detailed-overview
It is possible that a community is intended for a certain group of people, and ideally the community name will indicate that. If not, you can open up the community and check the sidebar. For example, !medicine@lemmy.ca is named 'Medicine Canada', and it is intended for Canadian medical professionals / Canadian medical news, while !medicine@mander.xyz is named 'Medicine', and it is the general community for the topic.
We didn't have to make 'Medicine Canada' on lemmy.ca, and in fact, there are many non-Canadian communities on lemmy.ca. It all comes down to what the community mods want the community to be about. The instance is just where they chose to set up shop.
In your case, the sidebar at !aliexpress@programming.dev says:
When in doubt, just check the community sidebar :)
Sub-forums here expect people from remote sites to comment on them. They're not just for local users. Most sites aren't going to have an Ali Express community on them for you to comment on.
Check the community's rules before posting, in case it's very specifically Ali Express discussion for software developers, and also so you know the nuances of that particular community, but don't feel like you can't engage with communities on the other side of the fence.
This whole space is best thought of "This forum I'm a member of, plus all these other things over there that I'd like to see, too!"
