How do suggested edits work?
On Stack Overflow (not Meta) I've noticed that sometimes my suggested edits are approved by the question's OP only. That is, no one else reviews the suggestion.
Strangely, these questions Can you approve edits to your own posts? and It takes two to tango? say it takes two or more votes.
Can the OP's vote alone approve an edit now (contrary to what the questions above say), or is this simply the system's way of dealing with edit clashes?
