I think the double exp weekends are a great idea and provide a fresh matchmaking outlet for social players but I think it would really benefit from a user created maps and gametypes playlist for double xp. Like if they chose ten or fifteen user content maps (+the gametypes associated) and ran them as a double xp playlist. If they did that once a month while changing the custom content along with the standard rotation of grifball, infection etc.. Id be prettty happy.
