@mcc IIRC Mastodon is older than Lemmy and the current move to Mastodon/Fedi happened in multiple waves, so it may be too early for higher expectations.
For stackoverflow I expect some degradation of quality since they accept “AI” generated content. This may additionally frustrate high quality authors and motivate them to leave. We’ll see.
What would a federated stack overflow look like if we were to invent it?
