As the news industry looks to reconstruct its business model, the journalists of today must reconstruct their skill sets for the growing world of online media that is why both new and experienced journalists are becoming entrepreneurial. The journalist of tomorrow will have to understand the value of content and how the business model is changing.
News organizations are looking for programmer/journalists. These are people who are able to report and present a quality story using multimedia, and having the skills to build and manage the platforms that present the stories.
The main thing is to understand the strengths and weaknesses of different media, spot trends and understand what new technology can do. Today, journalists need to have multimedia skills to tell stories through video, text, graphics, audio and photos. There are many resources for journalists to learn these skills, and many of the skills can be self-taught. One of the best ways to learn is through hands-on experience by starting a video blog. If you have some money to invest, buy a camera that takes quality photos and shoots video.
The new journalist will be a social journalist. This means engaging with your audience, promoting content and building personal brands with the help of blogging.
However, skills like good writing, ethics, news judgment, investigation and verification will always be important than ever as audiences search for credibility on the Web.
