I don’t necessarily see fracturing as a bad thing. I don’t know about you, but I didn’t find the askreddit discussions with 10,000+ replies to be particularly high quality. At least, no higher than what were found in much smaller threads. Fracturing can help make threads less overwhelmingly large. In addition to the other reasons why the redundancy can be a positive.
I understand why seeing ten different versions of ctechnology would get old, but that’s only when scrolling by ‘all’. Scrolling by either local or subscriptions will for the most part fix that. A downside is if you are subscribed to multiple ctechnology communities, in which case having a “multireddit” style feed would be nice. I think the Voyager app may offer that, I actually haven’t tried it out.
But when it comes to browsing ‘all’, seeing duplicates from different instances is a far sight better than having a centralized site where ‘all’ is dominated by low effort rage/horny/stupid bait.
