in reply to Update: Someone Else Posted First!

I think this happens when someone sees a new question and thinks he has a good answer for it, takes some time to craft a reply, and by the time he actually posts it, someone else has gotten in with a very similar answer. A kind of posting lag. When he discovers this, maybe he feels compelled to explain why he posted redundantly, perhaps to avoid a downvote.

Update: Looks like someone already said this.

    Additionally, it can be seen as a compliment that they did beat them to it.

    Posting lag is the main issue for me, combined with the lack of an ability to casually delete my posts. It's embarrassment, basically.

    Sometimes I try to add something with my "d'oh" update, so it doesn't just become "Solution. Update: jdporter already said Solution. I am a slow-witted idiot."
