“Maker Faire — sort of a combination science fair / county fair, with a hefty dose of Burning Man thrown in — has been happening once a year in this suburb on the outskirts of Silicon Valley since 2006. The first Faire drew about 20,000 attendees and 200 exhibits, and both of those figures doubled the following year. Now, with 70,000 attendees expected and exactly 600 exhibits, the Maker Faire is starting to feel a little, well, crowded.”
