My daily reading of several newspapers sparked this idea.
Newspapers have short paragraphs.
How many times have you seen an article in the paper that is one big chunk of text without breaks or sections?
There is a combination of copy and images.
How enjoyable would it be to read a newspaper without pictures, diagrams, charts?
Attention grabbing headlines hook the readers.
How many times have you read a piece after scanning the headlines?
With that being said, blogs should follow the format found in newspapers with many short paragraphs, visuals on occasion, and interesting titles.
