I recently introduced a new website that lists and honors breakthrough technology and innovative thinking: http://www.jumpintotomorrow.com. Everyday the site is updated, and everyday we hand out an award for the "Technology of the Day."  There are over 100 different technologies and innovations on the site spanning 24 different categories, from aerospace to fitness, business technology to nanotechnology with lots and lots in between. Visitors can group their interests from products they want to see and buy, to companies they can invest in to causes they want to join and more.  Because we're incredibly discerning about that which we put on the site, we hope that what's there feels more objective than subjective.  In the end, we're just trying to bring some more attention to companies and individuals doing really amazing things. 

Its not "millions" that have been sold, but the online stores and some brick and mortar stores are quickly selling out of their stock. All because of using (mostly) LinkedIn as a source of social networking contacts. By using LinkedIn in a certain way I've been able to  promote my book "How To Be A Creative Genius (in five minutes or less)" and interact directly with readers. No newsletter or SEO, just good old fashioned online networking.
