>>76253241But if OP is asking a question about a specific person, the thread is pretty much only relevant to the people who already know him.
Those who don't already know him aren't going to be able to answer the question, so it's pointless to explain it to them (other than as a courtesy I guess).
On the other hand it's also true that someone who doesn't know him could decide to learn about him for the thread, or even participate with general knowledge that isn't specific to that particular guy, so yeah, OP should've at least called him "youtuber speed" or something.
