When I started my Master's degree, the professors never wanted to hear speech in first person singular. They suggested using an impersonal third person pronoun, "one" or a historical third person plural, "we." Their positions might have changed over 36 years, but certain caveats probably have not. The biggest blunder people fall into is speaking personal opinion. The writer, like the good journalist, is to be objective, to just lay out the facts. Following that, one can explore the different reasons for the facts before putting forth their own idea as to why things are the way they are and what exactly can the writer or someone with a similar or even more developed point of view do, preferably someone able to make a change or lend their hand toward a solution.
