Drupal Gardens is Acquia's forthcoming “Drupal-as-a-service” offering, based on pre- released Drupal 7 code. Acquia, the main commercial company behind Drupal, is planning to release the service officially later in 2010. 

My colleague Adriaan Bloem has produced a short briefing answering two important questions that have emerged around Gardens:

1. Is it oriented more towards simpler use cases like blogging, or more complex services that make up traditional websites and community platforms?

2. Does it target Drupal novices, experts, or neither?
