>Today, with a mobile phone, you can take high-quality photos as a camera does.

I disagree, but I don't have a crappy camera either :) It is all about the conditions - in bright sun and nothing moving, a phone does okay. 

>Perhaps, people think that they don't have a content that will attract the auidence's attraction

It is not the topic that attracts attention, it is the development and delivery of ideas. People look for a great topic, when there are many - where they fail is in the execution of imagination and their willingness to practice delivery.
