One of the most significant elements I learned from document designing is the principles behind it. Diana Reep (2006) shows us that we should focus on page balance (the "visual weight" of a page), proportion (size and placement of elements), sequences and consistency in order to serve the document's purpose well.
Besides, as a blogger, I learned the importance of being an ethical blogger and how vital it is for a blogger to be accurate in sharing information, as well as to be sensible to certain ethnic groups and different cultures to preserve the image of being accountable and responsible in the world of information. (Cyberjournalist.net, 2003).
Hence, IPD is a true subject that bloggers should learn in order to sharpen their media literacy skills.
