Why I love Drupal 7
One of the great things about Drupal 7 is the ease of rolling out new sites, especially in combination with Drush. I recently rolled out 3 sites with a total cost of my time of 3 hours, about 1 hour for each site to register the domain, setup the credentials and database, install Drupal, and pull in the content from the previous static site. So cost to me is minimal to perform those requests from friends/co-workers/family to roll out sites for them. Plus, with the ease of use of D7 I now don't have to worry that they won't be able to figure out how to maintain their site.
One I can share is Go Bike where a somewhat insane friend is banking on the idea that she can start a business based around hauling compost by bike, and other assorted services. Crazy like a fox. I wish her the best of luck.
