I was thinking about it, and I don't think I've ever seen a child playing Magic. Children play Pokemon, Yugioh, whatever other thing is current. I've been to plenty of tabletop gaming stores and a few tourneys, a couple PAX's, and it was around during my own youth, and I've never seen anyone under the age of 13 playing MTG. When I was a kid it seemed too complicated to bother with and all the other kids agreed and stuck to kiddy shit.

My friend works for a credit union that only has like 8 branches but he gets paid a decent salary full-time to manage their website/servers/other software.
