Done works for a small publisher and has eCommerce on their website, but they're not satisfied with their web host. What does Leo recommend? Leo says that Squarespace, who is a sponsor, is great. They're very secure and have excellent service and support. You can even do a two-week trial to see if you like it. There's also Soft Layer and WordPress.com.
Leo also uses Drupal for TechGuyLabs.com, and he recommends BlackMesh, Heroku, and Contegix for managing your Drupal systems.
