Jason over at 37Signals has a great post on the fundamentals of repackaging content. It’s a proven business concept and it is good to see how it can work online.
Here’s the condensed version:
1st Money: Get your ideas vetted out on your blog, sell ads on your blog.
2nd Money: Make a PDF book or your learnings and sell it.
3rd Money: Make PDF into book and sell that.
4th Money: Hold a conference based on the subject of your book. Charge for that.
