I sometimes see some information, like post score, being updated by itself, without having to reload the page. Other things, like edits, require reloading to see.
What things are updating automatically inside posts via this live refresh?
From personal observations, this is the list of "live" information in posts:
Time stamps: (rate of refresh: one minute)
Banners (requires clicking to load)

If anyone observes anything else, feel free to add it here as well.
