I love tips. They're short, sharp and stuff you can use.
The eLearning Guild has just published a new ebook available to Guild Members:
68 Tips for eLearning Engagement and Interactivity. It's a compilation of practical ideas and tips from 11 individuals, myself included, who will be presenting in an eLearning Guild Online Forum this July.
And if 68 tips isn't enough for you, be sure to check out the Kineo website for another 79+ elearning tips.
