How do suggested edits work?
Whenever I edit any question, it displays a message:
Thanks for your edit!
This edit will be visible only to you until it is peer reviewed.
So I always wonder who does this peer review? Is it an automated system or, a manual process by moderator or high rep users?
Sometimes I get +2 reputation in a few seconds, but sometimes it takes time like half hour or more than hour. Why there is such delay?
