The Maker's economy is to my mind a sort of micro business economy. Rather than being defined by a job, a maker is someone who perhaps works a job, but also pursues a creative passion that they're bringing to market.
But a maker of what? Technology is moving so fast that you can invent a craft for yourself.
An illustrator making show posters for local bands, and also making their own greeting cards for sale in cafes and bookshops in their community would know this. It's a short staircase from that to self publishing graphic novels, children's books, and board-games; each a passion project, but also a product. With a bit of guidance, these products can form the basis for a business.
This economy is already happening in bedrooms and home offices, but could entice more to join it if there was a place that facilitated some of this learning. As it is now, those that are part of this economy are self taught, self-motivated creators with a working understanding of social media and where things are going next. That's a smaller segment of society, but they're also a built in trainer base - going around tutorializing their work for the internet at large. So much of their audience are encouraged to try now after seeing it demonstrated online, but don't necessarily have the equipment to try.
What's needed to facilitate this is a dynamic laboratory space that's open for use to the public of all ages. A place where someone can walk in and say "I've heard about this thing where you get to do X, but I have no idea where to begin." A workshop space, where a video journalist can give a few pointers to aspiring vloggers, or a social media expert can discuss the new species of marketing that continue to evolve month by month. A place where hardware resides that you can use to bridge the gaps between your ideas and the market.
