I don't think they are the most numerous games, SP games are. And certainly not even close to a majority of players. I would roughly guess only about about 10-20% of the total number of MP players play blitz games.

I'm also not sure there is a dichotomy between people who are good at blitzes and those good at long term games- almost everyone I can think of who plays blitz games plays other dominions multiplayer games as well.
