The article missed the mother of all Lists that turned into billion dollar business during last dotcom boom - Yahoo! Directory. It is unfortunate that Yahoo! shut down a service with lot of potential specially in the mobile world. Just think of possibility if you were starting with the Yahoo! Directory, making it mobile friendly, location aware, and providing users the ability to favorite, specific entry, add to the directory, comment on entries and directories. Majority of businesses today have online presence. Starting from scratch is difficult. Getting users to build a list from scratch is difficult. Offer them a pre-built list/entries based on location and let them refine it.
