People write to convey a thought, to vent, to share. People write for the reader, trying to put themselves in the shoes of those who want to take something out of the hundreds of characters that make a post. Bloggers try to capture the reader’s attention, the reader’s interest, and try to stimulate passions, emotions and imagination.
It is possible that often, not always but often, those who write do so in function of those who will read.
Perhaps I am creating a big controversy with this claim. After all, this is just my opinion and it can be debated.
