Maybe extremely hard, but nevertheless the Yahoo creation process is being duplicated at:
which is building the Open Directory. As a matter of fact, there continue to be many "public space" benefits of the early internet which are protected by the Gnu Public License(GPL), and therefore are likely to remain public. Please take a look at http://www.fsf.org to find out more about the free software movement.
The mail archive for lbo-talk resides on a computer whose operating system, Linux, is protected by the GPL and widely available at no cost. The software that runs about half of the web servers in the internet world, Apache, is free, open source software.
I don't dispute that internet capitalists continue to harvest, package, and market these public creations for profit. There is evidence though, that the capitalists are to some extent convinced, embarrassed (or gently extorted) into giving back resources to the communities from which the assets arose.
