The Lemmy devs operate lemmy.ml, but it’s far from being the most active one (it’s currently the 5th): lemmyverse.net/?order=active_day
Large instances admins? The most active communities are spread across dbzer0, lemmy.world, programming.dev, lemm.ee, feddit.de, etc.: lemmyverse.net/communities?order=active
The main difference of Lemmy compared to Reddit is the ability that communities have to walk away, as I explained in another comment: discuss.online/comment/5393546
Importing posts and comments could cause a security risk if someone would to abuse that function.
Even Mastodon doesn’t support it
Mastodon currently does not support importing posts or media due to technical limitations, but your archive can be viewed by any software that understands how to parse Activity Streams 2.0 documents.
That leaves me with just Reddit, so I’m stuck going back regularly.
Have tried posting about an alternative forum on Reddit, that allows third party apps? I’ve done that after messaging the mods in some communities, some of them were quite receptive
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?
