Infinite scroll is one of the most obvious. Infinite scroll promotes content consumption and not creation and is one of the most addictive patterns in web and app design. It's also less dense and totally irrelevant to what made reddit great, which was niche discussions and not image macros or whatever.

Compact and Classic mode aren't less dense - you can switch to those in the top right of the feed.

But I do agree with the infinite scroll point, or at least the way they implemented it.
