There has been a number of comments from people yesterday including Mark Attwood , Monty Widenus ,Monty Taylor ,Ronald Bradford , Arjen Lentz , Lewis Cunningham , Jeremy Cole , <a href=“http://pbxt.blogspot.com/2008/07/drizzle-goes-back-to-roots.html>Paul McCullagh,451 Group ,Matt Asay , Assaf Arkin , SlashDot , Builder.au and MySQL HA .

The Drizzle Launchpad project has reached 5th on a Google Search .

Unfortunately, not all uptake and feedback was positive. The official Wikipedia page for Drizzle was marked for speedy deletion almost instantly, and within a few hours permanently deleted.
