How come I just earned the Autobiographer badge to go with my Yearling badge? I just earned the Autobiographer badge to go with my Yearling badge. It was my own fault really: I filled in my profile. It bothers me a little because I thought that having **no other badge than Yearling** was unusual. Is that right?

You fulfilled the requirements for the two badges mentioned so they were awarded to you. Why does that confuse or bother you?

As for the Yearling badge being the one and only, I suspect that applies to a fair number of others. Many people come to the site, post a question or answer or two and disappear. If they get the required 200 points, after a year they get the Yearling badge. Not unusual at all. It's just that in your case you've come back.
