You can cater for everyone. Have winners play winners, and losers play losers so after the first round or 2, people are playing other teams that have similar results, and hopefully skill, whilst still catering for those of us who wish to take it a little more seriously.
I'm obviously not going to make a living out of it, but where a cash prize is offered, it creates more motivation to win, and with that comes frustration when your teammate is not playing at a level which you are happy with. I have fun playing 2v2's with friends, I hate nothing more than playing Random 2v2's.
