Any suggestions for channels to target? We're too cash-strapped to try a shotgun approach with Google Adwords or similar. Our exposure at Maker Faires has been one way for us to get the word out to about 200k people a year, in person. The reception has been phenomenal, and we received Editor's Choice at this year's past Bay Area Maker Faire. Kids and adults (with a roughly even gender split) love to learn about how things work, but not much attention has come back to the website.
