The internet makes it easy to write pretty much anything without any backlash, and I believe it has turned our society into a bunch of assholes. When we were kids we said everything that came into our heads, and someone: our parents, grandparents, older siblings etc, would smack our mouths and shame us for saying something rude or mean or inappropriate and that's how we learned to sensor ourselves. That's how we learned to get along, to be nice, to control our feelings, and to think before we talk. But now, there is no one there to sensor us when we are too stupid to sensor ourselves and the result is a bunch of little pricks spouting off about everything with zero consequences. Read the comment section of pretty much any internet article and you will see the lowest of the low of our society. That lack of thought and control has trickled into face to face conversation and now people are just plain rude all the time.
Anonymous is also a means of chickening out. There are bloggers who are actively trying to get published, have 3 or more books written, talk about their journey to find an agent etc. etc. and yet they are completely anonymous. No name no city, no picture no personal profile. No way whatsoever to find out who this person is. I don't get it. The #1 reason to blog is to build a platform but you don't want anyone to know who you are? I always think people who go anonymous are little scaredy cats and my respect for them drops just a little bit. If you don't believe in what you are writing/producing/thinking enough to put your name and face on it then why should anyone else? If you are so scared to take credit for what you have written then you must think it isn't very good. If you thought you had created the next best thing in literature you would be telling everyone you wrote it, but if you had a few hundred pages of crap on paper you might not want anyone to know it was yours. I get it. It's scary. But success doesn't come to those who hide behind their anonymous internet IP address.
Anonymous has it's place, I'm sure it must even though I can't think of a good example right now. But my personal opinion is that it cripples people. Step out into the light and take your hits and disses. Learn from it and grow into someone better. A better person, a better writer, a better painter, a better comic etc. Stand by your words and actions, don't throw shit into the wind and then hide from the shitstorm like a coward.
