design

Good site:
http://diglib1.amnh.org/
Strong design concepts include: good use of repetition throughout the site; good alignment; easy navigability; good color contrat that create a mood that helps users organize and understand content.

Bad sites:
http://home.comcast.net/~dboals1/boals.html
and
http://www.historycentral.com/

The moving text is paticularly a bad feature; it is distrating and annoying. There is no alignment in the table (or elsewhere). Graphics and content are terrible. Nothing is intuitive.
