TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
Arlen Walker (arlen -dot- p -dot- walker -at- jci -dot- com) gives a very good description
(as is his wont) of Application Notes.
One thing I would add...
Another reson for *short* app notes is that Tech Support often has to
fax them to a customer.
Fewer pages=lower fax costs, fewer chances for transmission errors.
