I stumbled across this question and I was unsure whether it fits SO requirements for a question. My initial thought was "No" because it seems like a Yes/No question with a prompt to do research for them.
But then I thought as I don't know G-Talk/W8-Messaging maybe this is an obscure enough question to warrant having to ask an expert.
I seems like the correct course of action is probably to flag it with an explanation of my reasoning, but I don't think the moderators get back to people if they disagree with the reason. I'd like to know so I can flag up stuff correctly.
What is your opinion on the validity question?
