I'm just marvelling at the ingenuity of some online companies such as
Schmap Guides or
Threadless. So now the concept is spreading from books (the whole Chicken Soup for the Soul series) to other items as well.
I suppose it's not entirely new. Linux, and other open source systems have been around for a while, they're all community driven, and have spawned several companies like RedHat and
Platform Computing.
** I don't work for any of the companies listed.
