I'm on Fark more than I used to be on Reddit. It's still my go-to for political discussions and kept me sane during the Trump years. Honestly, the community is pretty good there and there's a nice balance between insightful comments and snark. But Reddit was better for hobbyists, niche interests and tech discussions and I'm hoping those communities will develop here on Lemmy.
Reddit and Lemmy have better UIs than Fark. Fark shows websites as thumbnails rather than the content as the thumbnail, so it's both less engaging and less descriptive.
Like, this should really be a thumbnail of the desert: https://i.imgur.com/M8RhHli.png so it makes you want to click on it, and also having the ability to preview it would be nice too. Small things like this can make a huge improvement.
