Lee, it all depends on the subject matter my man. If I'm very interested in the details, I will read on and on....never getting enough if I'm into whatever it is. If I'm remotely interested, I'll scan the highlights of the article.

Text heavy can also be detrimental if used in certain situations where images might better tell the story.

One last thing....get it all down on paper and on screen, then see how it looks and feels. Manipulate your text as needed after you get all the important facts down.
