In the past I’ve written about “read-only” cultures—cultures in which people passively consume culture created professionally elsewhere. That’s the couch potato. That’s your four-year-old (but not your six-year-old) with your iPod. Think: lost to another world, while also lost to this world. Such read-only cultures can be contrasted with “read-write” cultures. These are cultures in which amateurs create their own culture, or versions of culture, and share that creativity with others. Think remix videos on YouTube, or photos on Flickr, or Wikipedia, or the links and RTs on Twitter. Amateur, however, not in the sense of amateurish. Some of it is; much of it isn’t. But whether it is or isn’t, that’s not the point. Instead, think amateur in the sense of people who create for the love of creating, and not for the money.
