The Emerging Economic Paradigm of Open Source

Family and friends, mostly those not involved in the tech industry, caution me about releasing my code via open source. It is difficult for them to understand how I can possibly make money by giving away my source code. Bruce Perens has written The Emerging Economic Paradigm of Open Source that addresses this issue in depth.

GravityZoo

Up until now I was not aware of any direct competitors to NewIO.
There were similar technologies, but nothing that closely resembled
it. However, I noticed this article on slashdot:

This is about a company called GravityZoo (http://www.gravityzoo.com/)
which appear to be doing pretty much the same thing as we are. So far
they appear to be proprietary and only have a MS Windows client, so I
see no reason to stop working on NewI\O, yet.
