Found this gem on [CreativeBits]:
InTips is a “tip of the day” plug-in that helps both novice and experienced InDesign users learn to use the program more efficiently.
[InTip’s tips and tricks] for Adobe InDesign were written by bestselling book author David Blatner as a way to help publicize the power of InDesign and its plug-in technology. Blatner notes, “I consider this ‘promoware.’ InDesign users get free tips, and we get to spread the word about other cool InDesign products. Everyone wins!” (Hat tip: [ID: Tip-A-Day Giveaway!])
