Scratch was conceived and written by Scott Barron, Ruby on Rails extraordinaire. Scott is also the author of the deliciously contrasting Elite Journal package. Elite Journal is a complete, multi-user web log platform. It is nothing at all like Scratch, and Scratch is nothing at all like it, despite sharing code.
Scott has been writing web applications for about 8 years now and has many personal and professional Ruby on Rails apps under his belt. He would be very happy to do freelance RoR work for you. Drop him a line at firstname.lastname@example.org for a quote. He does not disappoint.
