1. I really enjoy the obvious freedom and creativity portrayed in each artwork. Each piece takes into account location, population, public lens, and even style to illustrate a very specific message. These messages, because of their simplicity, generate a sense of open-ended questioning that people of all ages can relate to. The various interpretations are what make works like these fun to look at. (I am much too lazy to fix my dangling prepositions.) Political or social messages appear to be a major theme, but they take on a hint of comedy due to exactly how or where they are posted. I agree they are magnificent works of art. I smiled looking at them, even chuckled. That is enough for me. I am Switzerland with sensitive issues, so none of that here.
2. Anything can be viewed as artistic. It all depends on perspective-- the willingness of the beholder to view it so. Everything, even the simplest object in the world, is art in my mind. Viewing things from such a perspective opens the mind and garners a certain appreciation for the universe and one's place in it. As far as les noms de plume, they are applied for a number of reasons. Sometimes they are used to hide behind. Other times, they create an alternate persona. At the most basic level, however, they are used to create and personify an idea. This idea is used as a conduit and a front to share perspectives on certain subjects. Other ideas gain power when they come not from a vulnerable human, but from an immortal existence. Many leaders in the history of mankind have utilized art and symbols to represent them and their campaigns. A man can die, but ideas live on through the ages and personify the struggle of the people behind them.
"Ideas are bulletproof."

Examples of symbolism, art, and idea-based identities as shown in the 2006 film, V for Vendetta.
3. Whether or not one wishes to project themselves is the question that must be considered. Some write just for themselves, to relieve the various stresses of life. However, writing for an audience as well as oneself is important to better oneself as a writer, as well as to develop a presence that transcends one's life. People may never remember your name, but a story is passed through generations.
