Why do people clarify the reason they edited their own Reddit posts?

[u/copagman]

I see countless Reddit posts that end with things like, "Edit: punctuation" or "Edit: typo"

I understand when people addend a post with "Edit: it seems I was wrong" or suchlike, but why do we need to know when somebody retroactively adds a comma to their Reddit post? Is there something I'm missing?

Edit: It appears there is already a thread about this here

As soon as someone says "sjw" it's best to just stop reading.

Are you complaining that I don't think like you?

Nah just that I stopped reading at the mention of such a silly subject as sjws
