Hi! I'm Dane Carlson, and welcome to the Business Opportunities Weblog. I've been publishing this website, by myself, and sometimes with the help of others for over twelve years now. You'll notice two things about this site right away:

  • We have tons of content. In fact, since November 2011, I've published more than 26,000 posts on thousands of different business ideas and opportunities.
  • We don't sell much advertising. In late 2013, I realized that by selling advertising, what I was really selling was my readers. In 2014, I've already radically cut down on the number of ads and will hopefully keep cutting.

Wired: “New Yorker Joshua Kinberg is a bike messenger of a different stripe. Instead of ferrying legal papers between lawyers, he uses a homemade, wireless, bicycle-mounted dot-matrix printer to spray protest messages in the street.”

The printer is made out of five solenoid-triggered spray cans, loaded with washable chalk and mounted on the back of a bicycle. A laptop computer translates messages into a 5 by 5 pixel pattern, and then based on the speed of the bike sends firing commands to the solenoids. Messages appear on the street, from the back of the bicycle, like ticker tape.

It’s awesome technology that today is being used for street protests, but tomorrow could be used for all manner of advertising.

Watch the video. It’s amazing.
