To be honest I think most of the really awesome makers don't usually show up at Maker Faire. 95% of the exhibits are of the "Look ma I put a servo inside a puppet" variety. Very few of, say, the Hackaday-front-page caliber. There are some, but not enough to make it feel mindblowingly awesome.
I'd say there's no point really for individuals unless you're selling something with a decent profit margin. Publicity and talking with people is easier to get online.
