With any online community the group who consumes is far larger than the group who contributes, and I suspect with Reddit the people who are looking for community (especially those participating in mostly text-based subs) are few and far between compared to the huge number of users who browse big subs / the front page casually for memes, entertainment news, and cat pics.

The things which drive me nuts about the redesign are mostly things that drive me nuts because I comment far more than I post, and participate in a lot of discussion-heavy subs. Navigating comment trees is more difficult, lots more is hidden by default. Far fewer topics fit on a screen with the card-style layout that has huge previews. The old layout is information-dense, readable with minimal clicking to expand things, and fast.

But those are exactly the kind of changes that someone just browsing would be indifferent to, or even appreciate. The images/videos they're scrolling through are now big, front, and center. Many probably don't ever venture into the comments to begin with, of if they do, they're just seeing if the top comment is a good joke or not.

Wildly different use cases.
