Eh, that is kinda the appeal of Reddit, and its alternatives. Finding smaller communities of likeminded individuals that you can group into a tailored feed.
I always say the magic of this model is that it’s not just a firehose of every possible interest, it’s more like a shower of dozens of tiny handpicked jets. It just happens that on Lemmy, the “All” feed is still reasonably tailored to the main demographic here. That being tech nerds who dislike Reddit’s recent decisions enough to make a change.
Same honestly. And if I ever ask a question that someone might think is a duplicate, I link to that question and say something like “I found X, but the answers here don’t reflect Y”.
