Guy Kawasaki is one of the original marketers responsible for the success of the Apple Mac. 

He popularised the 10/20/30 rule which I wish more Powerpoint Presentations should stick to. 

To keep an audience engaged a powerpoint should have no more than 10 slides, be 20 minutes or less and use no less than 30 point font.

Maybe something similar exists for thought leadership. We see success from posts that keep roughly to a 1/10/100 format.

To make a point that resonates, an insight should be written for one person, take about 10 minutes to produce and be around 100 words.

Write for 1 person - you’ll make your point more effectively if you know who it’s for.

Write your content in 10 minutes - writing your post in less than half an hour means you keep your spark of inspiration.

Most content should be around 100 words - most readers won't sit through more than a few hundred words.
