But wouldn’t it be great if the knitting community (for example) on beehaw.org, lemmy.ml, lemmy.world and feddit.de would be merged for me into one entity for a better browsing experience?
Why wouldn’t they merge on one instance? Seems easier, and can be done today compared to having to ask the developers to implement a complex feature.
And on Lemmy some instances duplicate everything. For example beehaw
Are they not allowed to?
Beehaw exists for people who wanted a heavily-moderated space, and they seem to be doing well activity-wise. Do you want to force them with the rest of the instances?
