I highly recommend users setup their subscriptions, and set their default feed to subscription and new. This will get them engaging with conversations. Use the All feed to find new stuff to subscribe to. This is a fun experience.
It is a better way to sort during normal hours, but unfortunately I work a weird shift (4a-12:30p EDT) and the "new" page doesn't seem to change much during my normal breaks and lunch times and activity doesn't really seem to pick up until around 6:00 p.m. local time, which isn't far off from when I need to be in bed. We need to get some Australians on this platform.
