Today's question comes from Glenn, who asks why I haven't built a marketplace for buying and selling successful niche websites. There are several marketplaces available where you can buy and sell niche websites, including Flippa (a past sponsor; http://www.flippa.com/). Do you have a question about buying a niche website? Record it at http://www.askpat.com/. Today's sponsor is TunnelBear. To learn more and to try TunnelBear for free, go to http://www.tunnelbear.com/askpat/.
