Early Maker Faire (in the Bay Area) was a mix of art booths/vehicles coming out of Burning Man storage and independent makers showing their projects and inventions. Then it rapidly commercialized with company booths taking most of the show space, and then it finally imploded financially. The recent resurrected version is less commercial, much smaller, and aimed more at younger children and their parents, but is overall not that far off from the Make origins.
Open Sauce is very much Creators (content and otherwise) and independent makers, growing in scale every year. It works well, in part because the company/sponsor booths are no larger or flashier than the hacker/maker booths.
