Wow, that's pretty bad. Logical consistency was clearly not a guiding principle of this redesign.

There is a consistent principle behind those choices: rectangles with slightly rounded corners are clickable, while rectangles with semicircular sides (“pills”) are not clickable. It's confusing because I've never seen another site that distinguishes clickable elements in that way, but I can imagine we'll grow to find it intuitive with enough usage.

For sure we can all learn through trial and error pretty much any UI. And I know there are complaints any time any big site tries to do a redesign.

But a good UI should be intuitive for a first time user. This seems objectively worse.
