How does writing (and/or designing) for a public audience affect what you say, how you think about your work and what difference it might make?
I think that this question is pretty important. When writing for a public audience, it is important to take into consideration the actual audience. For example, if you're a scholar writing academic articles towards other scholars, you can make your writing dense and jargony and expect that your readers will understand what you're saying. If you're a scholar writing a middle school science textbook, you have to know to alter your writing to make sure that you're writing on their level.
This applies to all sorts of writing. It's not solely a matter of comprehension, but also important for keeping readers engaged and interested. First though, you have to make sure that you have identified and understand your target audience. This can sometimes be a challenge, so I found a couple interesting articles that are helpful. 6 Steps to Decoding Your Target Audience and 5 Tips on How to Identify Your Target Audience are both helpful!
