Reddit is still one of the few sites left that provide user content openly. FB+Instagram+Twitter are entirely inaccessible if you don't have an account, and a lot of forums do things like only show images to logged in users.

I've found the Reddit experience much worse with recent changes. When you land on Reddit from a Google search comment threads are only 1 level deep with a max of only a few replies shown, so you have to load a new page for each response you want to read. It's one of the worst UX I've seen considering that landing from search is probably the most financially lucrative use patterns Reddit has.
