The next worst is when there are only a handful of search results and the top one is a forum post with replies saying the answer is easily available, and the OP should have used Google first.

The remaining results being archives of that first one.

No, the worst is when someone posts their bug and then others start asking questions or trying to figure it out, then the original poster says "thanks guys, I was actually able to figure it out". And doesn't post the solution!!! Just so infuriating.
