Business of Software
The "Business of Software" was a forum hosted by Joel Spolsky's company, Fogcreek software. Business of Software is also the name of a book by Eric Sink, one of the people who created the internet, and who was a moderator at the BoS forums. There is an annual 'Business of Software' conference.
My book "Choose Your First Product" is available now.
It gives you 4 easy steps to find and validate a humble product idea.
