Not everything works. I start a lot of projects that grow slowly, or else have been retired. But sometimes old dormant ideas resurface more useful than ever, so I leave these quiet projects up.
For a while I ran a blog, Street Use, about the ingenuity of people in repurposing technology and ways they made DIY tech. I also collected a long series of graphs forecasting the future for different industries and subjects. Extrapolations was assembled to assist me in making a larger forecast of a desirable future, a project-in-process called Protopia. I was infatuated with digital publishing about 10 years ago when such information was scarce, so I published a blog called Screen Publishing as a clearing house for best practices in e-publishing. It is inactive now, although the info might still be useful.
