Society can never "over" anything. Society is based on culture, our beliefs, stories and the way we think about the world. Feminism is where women are equal in society, which they can if they want to be. It just opens up doors and oppurtunities for them, and if women want that they can take advantage of it.
Will there be more DJs because of the internet? Yes, yes, yes. I wouldn't have found this little niche in society if it were not for the internet, so of course it will increase in time as communication becomes more advanced and a bigger play in people's lives. And more DJs is a good thing... it would simply mean more people are satisfied. Guys are more satisfied because they are getting more pleasure, and girls are more satisfied because they are getting more pleasure. This is a good thing, don't let anyone else tell you otherwise.
