If you’ve ever used Burnermap, you’ll know what a useful tool it is. In theory, anyway – it’s surprisingly difficult to find people at Burning Man even if you know their location, while at the same time it’s incredibly easy to run into people totally randomly. Burnermap was created by Micah Daigle and others as something free for us all to benefit from. Taking that spirit further, Micah just announced Burnerhack, an event coming up in San Francisco for the open source and maker community. They’re taking advantage of “[freespace]”, a 14,000 square foot warehouse in the city’s trendy South of Market area that is being offered for free to San Francisco’s creative community for a month.
