buzz said:But, isn't the whole point that it isn't obvious that it's "gamer sign"? What matters is that we know what it means. Much like the now-ubiquitous Jesus-fish was originally, it's supposed to mean nothing to people who aren't already in the know. Hence spreading the meme amongst the existing gamer populace.
The Jesus-fish is an excellent example - the symbol is a direct reference to the miracle of the loaves and the fishes. Non-Christians didn't understand the relevance, but the symbol was still picked from within the culture. Those who used the symbol did not have to go through loops of logic to understand why it meant them.
The play button is not part of gamer culture. That's my point. The connection between the symbol and gaming here is completely artificial. The as noted above, the A_V people use something that's at least related to audio and video. Pick an obscure thing from within gamer culture, and I'd not gripe. A d20, or "Krusk Lives!", or a stylized paper and pencil - something that outsiders wouldn't understand, but actually means something in context to me.
