At the new local site I'm playing with, I've posted a short audio piece from an interview with a local entrepreneur. The guy runs a website for couples called Our Divorce Agreement, and it's really a very interesting business model. It's highly automated, so almost all of his work deals with tweaking his price and his keyword advertising.
He got the idea for the site while working as a mediator. He realized that about 10% of all the couples he saw were very cordial and just needed a simple template that helped them determine all the things they needed to cover. That's an entrepreneur for you – always keeping an eye open for interesting niches.
