I've had this happen to one of my submissions too. It was this post: http://news.ycombinator.com/item?id=41988

I didn't put the authors name in title and it was edited to reflect that.

I believe in my submission I had put the authors name at the end, and it has now been moved to the front of the title. Either that or I'm just really tired.

They were minor edits for brevity, just the removal of one or two adjectives and conjunctions.

I.e., they were the types of things that if I were writing a paper and a draft reviewer suggested removing them, I would have said "ok".

But that's not the point.

Agreed. I was just wondering out of interest.
