I am referring to this question:
I started to answer the question, but as I wrote my answer, someone was commenting with the OP and I changed my answer as new information came to light (instead of two cases, only one, so just deleted one case). It is obviously a simple question that the commenter could have answered. When I realized that the commenter was getting more information, was it wrong of me to continue to write my answer and post it? I almost feel like I "stole" the question, but I started before I realized the person was gathering information. I debated deleting it for a couple minutes before posting it.
