Over the past few days, I've witnessed a remarkable surge in the number of communities on browse.feddit.de. What started with 2k communities quickly grew to 4k, and now it has reached an astonishing 8k. While this exponential growth signifies a thriving platform, it also brings forth challenges such as increased fragmentation and the emergence of echo chambers. To tackle these issues, I propose the implementation of a Cross-Instance Automatic Multireddit feature within Lemmy. This feature aims to consolidate posts from communities with similar topics across all federated instances into a centralized location. By doing so, we can mitigate community fragmentation, counter the formation of echo chambers, and ultimately foster stronger community engagement. I welcome any insights or recommendations regarding the optimal implementation of this feature to ensure its effectiveness and success.
