Anyone play BF Heroes?

I know that BF Heroes is still in its beta, but does anyone play it? What do you think about it and how do you think the play for free aspect of it will attract people to the gaming community that were never there before, because i think that branding the games under the Play for free title will attack a lot more people into shoot'em up games, even though this is a relatively "soft" introduction with it being a cartoon shooter.
