Artists create personas to protect themselves, it’s not a new concept. Assuming an alter ego allows freer expression of culturally inexpressible ideas.
A persona adds a layer of personal protection, as the public needs to work through an image to confront & understand an artist on a personal level.
This allows the art & ideas to speak for themselves (at least for awhile), instead of succumbing to the cult of celebrity. Fame brings money and excess, which are dangerous & corrupting influences to anyone.
With the rise of the Internet, anybody with a computer or mobile device can create their own online persona. Andy Warhol’s vision of everybody being famous for 15 minutes is now manifesting itself in all kinds of awful, weird, and simultaneously wonderful ways.
Online, people can be whatever they want without much repercussion, due to the layers of screening & anonymity. The cyber-world is sleazy & creepy, but also filled with revolutionary potential. Communication of ideas has never been faster, and people are starved for real information & discussion on anything & everything.
The downside of social media is that it allows a vehicle for evil & hate to spread its poison, especially when left unchecked, therefore it must be combated effectively & diligently. 
Innovative network television programming is virtually dead. Most of the best current films are documentaries created by independent filmmakers, as YouTube & Netflix are rich sources of engaging & serious independent film content. Hollywood needs to be largely understood as a waste of talent at this point.
No thinking kid (or adult that has survived with his/her brains intact) believes any corporate-sponsored news, which is 100% lies & half-truths. One thing I’ve noticed while researching and engaging in social media, is when reading an article on MLB.com, ESPN or NASCAR.com… I often find the comments just as helpful (if not more so) in terms of facts & ideas as compared to the article. Fifteen seconds of fame for the poster.
Dialectics in politics applies when long-term difficulties & seemingly hopeless situations are suddenly wide-open playing fields for opportunity & victory. Personas, when used correctly, allow elusiveness in being focal points for online influence & clout, which is necessary to revolutionarily transform & socialize our planet.
