I’ve seen a number of posts stating that they are worried that multiple instances will have overlapping magazines, like “Technology“. It’s true this will happen. But I don’t think it is a problem.
One thing I’ve learned from Mastodon, and I think it will apply to kbin as well, is that you don’t need to post for EVERYBODY on the internet. At some point, there’s a number — 1000 people, 10,000 people, or 100,000 people — where there are enough users where you can have an effective community and a nice conversation, without being so big that everything goes to sh*t.
In real life, we don’t expect to know everybody. We interact with people close to us. Maybe, this is fine in a federated community as well.
And, of course, there is still the chance that post will get really popular and percolate through the fediverse, for example, into the multiple “Technology” magazines.
In sum, I think the fediverse model will build multiple, interlinked, smaller but sustainable communities. If all you want is “reach”, it won’t be for you. But I think it will be good if you want community.
Especially since most of the platform is still fresh out of the box. It doesn’t even have a mobile app yet (Lemmy does, but it is a heavy work in progress, like Lemmy itself), but that it works well enough, and didn’t all implode immediately under all the Reddit traffic is a minor miracle.
