I have my viewing type set to "All" on my settings but when I go to the index page (lemmy.world), it's set to Local.

Not sure if it's an issue or just a symptom of lack of large communities yet but I also tend to see the same posts on the top every time ("If we want this to work out make content do not just lurk", "All the sad" and "important rulepost").

Edit: Also there's an issue when posting. I click "Post" and it gets stuck in the spinning icon despite my profile indicating my comment has been posted successfully.

Edit 2: Related to my second paragraph, I suggest changing the default sorting to Hot instead of Active. At least currently, Active keeps a handful of the same posts permanently on top, giving the impression of inactivity for newcomers used to Reddit. Hot will provide a more varied front page.
