What if, like me, they are voices considered to be in the center, assumed to be full of while privilege, not on the margins and not wanting to imagine much less create alternative, new worlds? I would argue that as an adjunct, someone over 65, and a farmer at the end of a half-mile hollar, that I am mos def on someone's damned margins. And who's to say otherwise.
John Seely Brown even talks about how the margins of open education create their own margins:
Open source communities have developed a well-established path by which
newcomers can “learn the ropes” and
become trusted members of the community through a process of legitimate
peripheral participation. New members
typically begin participating in an open
source community by working on relatively simple, noncritical development
projects such as building or improving
software drivers (e.g., print drivers). As
they demonstrate their ability to make
useful contributions and to work in the
distinctive style and sensibilities/taste of
that community, they are invited to take
on more central projects. Those who become the most proficient may be asked
to join the inner circle of people working
on the critical kernel code of the system.
Today, there are about one million people
engaged in developing and refining
open source products, and nearly all are
improving their skills by participating
in and contributing to these networked
communities of practice.
