Good interview with David & Forbes. Boy, this quote sums it up nicely:
“In the years before we took the company private, we had diversified into a number of business that were unrelated to our core service of managing digital advertising for buyers and sellers.
Our primary strategy after 2005 was to reverse that diversification and focus intensely on the core business. Once we did that, we realized that we had the opportunity to add new business, but we did so in a smarter way and in areas that were truly adjacent to the core business.”
